This paper provides a bio-based polyurethane foam (PUR) solution, following cradle-to-factory approach. The design of rigid PURs, reinforced with sustainable fillers have gained remarkable attention in "green" construction sector. Their marked performances make them viable solution for synthetic counterparts' replacement. In this work, functionalized hemp fibers and silica powders were selected as reactive fillers, imparting multifunctional properties to the designed PURs. Hemp underwent...
Intelligent composite materials and devices are attracting a great interest owing to their potential impact on various future life applications. To meet the growing demand for multifunctional materials, development validation of visible sensing behavior is highly desirable, but single wearable material still remains challenge be achieved. reach this goal, here we present intelligent fabric with piezoresistivity mechanoluminescence ability based layer-structured graphene-based conductive...
Abstract Leather is one of the most popular products across globe and holds a significant place in economy, while pollution, associated to traditional leather industry, far away on “green chemistry” principles. In this sense, polyurethanes, which exhibit tunable chemical structures by selecting suitable precursors, can fit specific requirements, developments green strategies make them important candidates for industry. This mini review briefly outlines recent development conventional...
Nowadays, the chemical industry is looking for sustainable chemicals to synthesize nanocomposite bio-based polyurethane foams, PUs, with aim replace conventional petrochemical precursors. Some possibilities increase environmental sustainability in synthesis of PUs include use and additives derived from renewable sources (such as vegetable oils or biomass wastes), which comprise increasingly wider base raw materials. Generally, exhibit chemico-physical, mechanical functional properties, are...
In the present work, a catalytic screening using most common heterogeneous acid catalysts was conducted, as raw material ethyl levulinate. Extensive catalyst revealed that Amberlyst-15 can be considered very suitable to promote DPE synthesis from levulinate and phenol. The use of allowed obtain 100% selectivity towards p,ṕ-DPE isomer, precursor for NIPU synthesis. A kinetic investigation conducted determine influence different parameters on reaction rate. Finally, mathematical model with...
The effect of alkaline lignin (AL) and sodium lignosulfonate (LSS) on the structure thermoplastic zein (TPZ) was studied. Protein structural changes nature physical interaction between were investigated by means X-ray diffraction Fourier transform infrared (FT-IR) spectroscopy correlated with properties. Most relevant protein observed at low AL concentration, where strong H-bondings functional groups amino acids in induced a destructuring inter- intramolecular interactions α-helix, β-sheet,...
Two types of lignin, alkali lignin and lignosulfonic acid sodium salt, are blended into thermoplastic zein through melt mixing in order to develop biodegradable insulator materials for multifunctional applications electronics. The effects type content on the dielectric properties resulting bio‐nanocomposites investigated. results indicate that, by modifying structural arrangement with use it is possible obtain characterized tunable properties. containing low amounts derivatives exhibit...
To obtain sustainable food packaging materials, alternatives to traditional ones must be researched. In this work, two different kinds of zeolites, i.e., a natural one, Clinoptilolite, and synthetic Zeolite Na-X, were mixed with thermoplastic polyurethane for the fabrication composites. Composite films prepared via hot mixing stage then by means compression molding process. Several TPU/zeolite composites produced filler concentration ranging from 5% 10%wt. Finally, obtained characterized...
Anisotropic aerogel-foam composites were developed by embedding a reduced graphene oxide (rGO)/chitosan aerogel directly into an open-cell polyurethane foam through in situ bidirectional freeze-drying process. The resulting possess both excellent compression-resilience performance and stable piezo-resistive properties due, respectively, to the mechanical of foams presence chitosan-based loaded with rGO. latter, indeed, provides outstanding electrical due its conductive parallel flat lamellar...
A vegetable tannin, a flavonoid-type natural polyphenolic compound, was used to promote the stabilization of polyurethane foams against UV radiation. Several were synthesized by using an isocyanate, and mixture ethoxylated cocoalkyl amine tannin. The content tannin varied from 0 40 wt %. effects water (used as blowing agent) on foaming kinetics cellular morphology investigated. Samples subjected accelerated weathering under radiation for 3 24 h, FTIR DMA analyses conducted assess performance...
Abstract Motivated by the hierarchical micro and nanoscale features in terms of porosity diatomite, production ceramic-graded porous foams with tailored porosity, obtained using it as raw material, has been proposed. The main challenge during foam-production process preservation diatomite nanometric addition other levels porosity. coupled use two techniques direct foaming (chemical mechanical), combined 3D printing inverse replica method, assured achievement of, respectively, microscopic...
Currently, the scientific community has spent a lot of effort in developing “green” and environmentally friendly processes products, due contemporary problems connected to pollution climate change. Cellulose nanocrystals (CNCs) are at forefront current research their multifunctional characteristics biocompatibility, high mechanical properties, specific surface area, tunable chemistry renewability. However, despite these many advantages, inherent hydrophilicity poses substantial challenge for...
