In the present work, cellulose nanowhiskers (CNWs), extracted from ramie fibers, were incorporated in polylactide (PLA)-based composites. Prior to blending, PLA chains chemically grafted on surface of CNW enhance compatibilization between and hydrophobic polyester matrix. Ring-opening polymerization l-lactide was initiated hydroxyl groups available at yield CNW-g-PLA nanohybrids. PLA-based nanocomposites prepared by melt blending ensure a green concept study thereby limiting use organic...
Novel potentially biobased aliphatic-aromatic copolyesters poly(butylene succinate-co-butylene furandicarboxylate) (PBSFs) in full composition range were successfully synthesized from 2,5-furandicarboxylic acid (FA), succinic (SA), and 1,4-butanediol (BDO) via an esterification polycondensation process using tetrabutyl titanate (TBT) or TBT/La(acac)(3) as catalyst. The characterized by size exclusion chromatography (SEC), Fourier transform infrared (FTIR), (1)H NMR, differential scanning...
Fully bio- and CO2-sourced non-isocyanate polyurethanes (NIPUs) were synthesized by reaction of carbonated soybean oil (CSBO) either with biobased short diamines or amino-telechelic oligoamides derived from fatty acids to achieve respectively thermoset thermoplastic NIPUs. Biobased vegetable oils first obtained metal-free coupling reactions CO2 epoxidized under supercritical conditions (120 °C, 100 bar) before complete characterization FTIR, 1H NMR, electrospray ionization mass spectroscopy...
Bio- and CO<sub>2</sub>-sourced non-isocyanate polyurethane (NIPU) microcellular foams were prepared using supercritical carbon dioxide (scCO<sub>2</sub>) foaming technology.
Abstract This review reports on recent advances in the design of biodegradable polymers built from petroleum and renewable resources using reactive extrusion processing. Reactive represents a unique tool to manufacture upon different types modification cost‐effective way. Partially based our ongoing research, ring‐opening polymerization polyesters will be approached as well chemical polymers, particularly natural polymers. The development environmentally friendly polymer blends...
Free-radical-initiated grafting of maleic anhydride (MA) onto poly(butylene adipate-co-terephthalate) (PBAT), a biodegradable aliphatic-aromatic copolyester, was performed by reactive extrusion. 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane used as the free-radical initiator. The peroxide concentration varied between 0.0 and 0.5 wt % at 3.0 MA concentration; 1.0 5.0 concentration. reaction temperature maintained 185 degrees C for all experiments. Under these conditions, 0.194% 0.691% grafted...
The crystallization kinetics and morphology of biodegradable double crystalline poly(l-lactide)-b-poly(ε-caprolactone) diblock copolymers (PLLA-b-PCL) was studied in a wide composition range by differential scanning calorimetry (DSC) polarized light optical microscopy (PLOM). two blocks were found to be partially miscible according the variations their thermal transitions with composition. PLOM results showed that PLLA crystallizes spherulitic superstructural morphology. Only when content is...
Shape memory properties of polymers represent one the most expanding fields in polymer science related to numerous smart applications. Recently, multiple-shape (multiple-SMPs) have attracted significant attention and can be achieved with complex architectures. Here, miscible PLLA/PMMA blends broad glass transitions are investigated as an alternative platform design multiple-SMPs. Dual-shape experiments were first conducted at different stretching temperatures identify so-called "temperature...
Abstract A new concept to build shape memory polymers (SMP) combining outstanding fixity and recovery ratios (both above 99% after only one training cycle) typical of chemically crosslinked SMPs with reprocessability restricted physically is demonstrated by covalently bonding, through thermoreversible Diels–Alder (DA) adducts, star‐shaped poly( ε ‐caprolactones) (PCL) end‐functionalized furan maleimide moieties. PCL network easily prepared melt‐blending complementary end‐functional star in...
Cross-linked poly(ε-caprolactone) (PCL)-based polyesterurethane (PUR) systems have been synthesized through Diels-Alder reactions by reactive extrusion. The and retro-Diels-Alder proved to be useful for enhancing the molecular motion of PCL-based systems, therefore their crystallization ability, in design cross-linked semicrystalline polymers with one-way two-way shape-memory properties. Successive between α,ω-diol PCL (PCL(2) ), furfuryl alcohol, methylene diphenyl 4,4'-diisocyanate...
Cellulose nanowhiskers (CNW), extracted from ramie fibers by sulfuric acid hydrolysis, were used as substrates to compatibilize binary polyester blends containing 50/50 (w/w) polycaprolactone (PCL) and polylactide (PLA). To tailor their interfacial energy fine-tune adhesion with the components of blend, CNW subjected different surface grafting means ring-opening polymerization. PCL PLA homopolyesters well P(CL-b-LA) diblock copolymers successfully grafted on resulting loaded into PCL/PLA...
