Nanocellulose is often being regarded as the next generation renewable reinforcement for production of high performance biocomposites. This feature article reviews various nanocellulose reinforced polymer composites reported in literature and discusses potential nanocomposites. The theoretical experimentally determined tensile properties are also reviewed. In addition to this, reinforcing ability BC NFC juxtaposed. order analyse cellulose-reinforced nanocomposites literature, Cox–Krenchel...
Carbon dioxide/epoxide copolymerization is an efficient way to add value waste CO2 and reduce pollution in polymer manufacturing. Using this process make low molar mass polycarbonate polyols a commercially relevant route new thermosets polyurethanes. In contrast, high polycarbonates, produced from CO2, generally under-deliver terms of properties, one the most widely investigated, poly(cyclohexene carbonate), limited by its elongation at break brittleness. Here, catalytic polymerization...
This work investigates the surface and bulk properties of nanofibrillated cellulose (NFC) bacterial (BC), as well their reinforcing ability in polymer nanocomposites. BC possesses higher critical tension 57 mN m–1 compared to NFC (41 m–1). The thermal degradation temperature both nitrogen air atmosphere was also found be than that NFC. These results are good agreement with crystallinity determined by XRD, measured 71% for 41%. Nanocellulose papers were prepared from Both possessed similar...
Abstract This review paper provides a recent overview of current international research that is being conducted into the functional properties cellulose as nanomaterial. A particular emphasis placed on fundamental and applied undertaken to generate applications, which are now becoming real prospect given developments in field over last 20 years. short introduction covers context work, definitions different forms nanomaterials (CNMs) most widely studied. We also address terminology used for...
Abstract Environmental concerns are driving interest in postpetroleum synthetic textiles produced from microbial and fungal sources. Bacterial cellulose (BC) is a promising sustainable leather alternative, on account of its material properties, low infrastructure needs biodegradability. However, for alternative like BC to be fully sustainable, ways dye need developed alongside production methods. To address this, we genetically engineer Komagataeibacter rhaeticus create bacterial strain that...
The effect of surface functionalisation bacterial cellulose nanofibrils (BC) and their use as reinforcement for polylactide (PLLA) nanocomposites was investigated. BC functionalised with various organic acids via an esterification reaction. This rendered the otherwise hydrophilic hydrophobic resulted in better compatibility (interfacial adhesion) between PLLA BC. A direct wetting method, allowing determination contact angle polymer droplets on a single nanofibre, developed to quantify...
An isolation method with mild mechanical agitation and no acidic extraction step from a mushroom substrate resulted in chitin nanofibers (ChNFs) large shares of retained glucans (50–65%). The subsequent nanopapers exhibited exceptionally high tensile strengths >200 MPa moduli ca. 7 GPa, which were largely attributed to the preserved mixture, imparting composite nature nanopapers. for ChNFs is notably different conventional process crustacean sources that do not incorporate where an removal...
Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can manufactured as simply producing paper? Here the production of membranes nanocellulose by applying a papermaking process is demonstrated. Manufacture nanopapers was enabled inducing flocculation nanofibrils upon addition trivalent ions.
Recent interest in the utilisation of greener materials has reinitiated natural fibres and/or fibrils as reinforcement for polymers.However, such bio-based composites often exhibit properties that fall short expectations due to (i) inadequate processing conditions, resulting filler agglomeration and poor dispersion within matrix, (ii) variations fibre properties, geographical seasonal variability, (iii) anisotropy themselves, (iv) high linear coefficient thermal expansion (v) incompatibility...
A new series of block polyester thermoplastic elastomers are prepared by a one-pot procedure; they show properties competitive or better than conventional materials and can be fully degraded after use.
The research and development of nanocellulose-reinforced polymer composites have dramatically increased in recent years due to the possibility exploiting high tensile stiffness strength nanocellulose. In work, environmental impact bacterial cellulose (BC)- nanofibrillated (NFC)-reinforced epoxy were evaluated using life cycle assessment (LCA). Neat polylactide (PLA) 30 wt.-% randomly oriented glass fibre-reinforced polypropylene (GF/PP) used as benchmark materials for comparison. Our...
Engineered living materials (ELMs) based on bacterial cellulose (BC) offer a promising avenue for cheap-to-produce that can be programmed with genetically encoded functionalities. Here we explore how ELMs fabricated in modular fashion from millimetre-scale biofilm spheroids grown shaking cultures of Komagataeibacter rhaeticus. define reproducible protocol to produce BC the high yield producer K. rhaeticus and demonstrate first time their potential use as building blocks grow 3D shapes.

Plastic pollution, more specifically from food packaging and containers which account for the largest share of 36% current plastic production, is one greatest threats to natural environment human health. Thus, development alternative renewable plastics are needed complement a circular economy reduce resource depletion.

Abstract Over the past 150 years, our ability to produce and transform engineered materials has been responsible for current high standards of living, especially in developed economies. However, we must carefully think effects addiction creating using at this fast rate will have on future generations. The way currently make use detrimentally affects planet Earth, many severe environmental problems. It next generations by putting danger economy, energy, climate. We are point where something...
Fully renewable macroporous thermosetting and UV-cured cellulose nanocomposites have been synthesized from medium high internal phase water-in-acrylated soybean oil emulsions stabilized solely by hydrophobized bacterial nano-fibrils.
Water-in-oil emulsions stabilized solely by bacterial cellulose nanofibers (BCNs), which were hydrophobized esterification with organic acids of various chain lengths (acetic acid, C2-; hexanoic C6-; dodecanoic C12-), produced and characterized. When using freeze-dried C6-BCN C12-BCN, only a maximum water volume fraction (ϕw) 60% could be stabilized, while no emulsion was obtained for C2-BCN. However, the ϕw increased to 71%, 81%, 77% C2-BCN, C6-BCN, respectively, 150 h after initial...
A novel robust non-woven sisal fibre preform was manufactured using a papermaking process utilising nanosized bacterial cellulose (BC) as binder for the fibres. It found that BC provides significant mechanical strength to preforms. This can be attributed high stiffness and of network. Truly green reinforced hierarchical composites were prepared by infusing preforms with acrylated epoxidised soybean oil (AESO) vacuum assisted resin infusion, followed thermal curing. Both tensile flexural...
"Hairy" bacterial cellulose coated sisal fibres were created using a simple slurry dipping process. Neat with BC to create (i) dense coating around the or (ii) "hairy" oriented perpendicular fibre surface. These used produce hierarchical reinforced polylactide (PLLA) nanocomposites. The specific surface area of increased when compared neat sisal. Single tensile tests revealed no significant difference in modulus and strength "hairy fibres". However, layer, mechanical properties decreased....
This article reviews the tensile properties of various plant fibre-reinforced polymers reported in literature. We critically discuss use fibres as reinforcement for production bio-based, renewable or green polymer composites. The these composites are compared against (non-)renewable engineering/commodity and commercially available randomly oriented glass (GFRP). Composites containing random short possess similar to GFRP at a lower overall part weight. Unidirectional offer better performance...
