To date, all epoxy vitrimer systems reported in the literature rely on addition of significant amounts catalysts to achieve dynamic transesterification reaction (TER). However, used vitrimers are often toxic and have poor miscibility with organic compounds, they may further comprise application performance like corrosion resistance. Moreover, reprocessing recycling properties highly dependent loading amount type catalyst. In this study, two hyperbranched (HBE) prepolymers synthesized then...
Strict isomorphism between butylene succinate and fumarate in poly(butylene succinate-co-butylene fumarate) (PBSF) was revealed by DSC wide-angle X-ray diffraction results. They adopt the same crystal modification, with only a little difference lattice parameters. The melting point of copolymer increases linearly increasing molar ratio enthalpy hardly changes, which meet requirement strict isomorphism. introduction unsaturated comonomer, fumaric acid, into PBS can enhance total...
Polyurethanes with covalent adaptable networks (CANs) have received extensive attention due to their recyclability and self-healability; meanwhile, how design regulate the structure properties of dynamically cross-linked polyurethanes biobased monomers is particular interest. Herein, we a new type polyurethane derived from polyol (castor oil) industrial bulk products: bisphenol isophorone diisocyanate. Furthermore, develop strategy rearrangement kinetics dynamic networks. The stronger...
To obtain a new type of biodegradable material with high toughness and strength used for fused deposition modeling (FDM) printing, series poly(butylene succinate) (PBS)-based polymer materials was prepared via blending polylactide (PLA). The rheological, thermal, mechanical properties as well FDM printing performances the blends, such distortion, cross section, interlayer bond strength, were characterized. results show that increasing PLA content, blends possess higher melt viscosity, larger...
Elastomers with high strength and toughness are in great demand. Previous research on elastomers focused mainly the design of new chemical structures, but their complicated synthesis process expensive monomers have restricted practical application these materials. Inspired by general filler effects, a strategy is proposed to remarkably enhance mechanical properties thermoplastic polyurethane (TPU) designing arrangement hard/soft segments using traditional compositions. By utilizing...
Recent plastic flow research has largely focused on commodity plastics (PE, PP, PVC, PS, ABS), yet a sizable share of other polymer types remains understudied. These non-commodity suffer from inconsistent definitions, complex classifications, and data gaps, which hinder accurate assessment their production, use, end-of-life management. This study develops dynamic material analysis to investigate 12 key "non-commodity" in China─including PET, PU, seven engineering plastics, three...
Real-time atomic force microscopy observation was carried out during crystallization in thin films of chiral poly(R-3-hydroxybutyrate-co-R-3-hydroxyhexanoate) copolymer, and the development details single lamellae banded spherulites are revealed for first time. The exhibit complicated growth behaviors: twisting, bending, backward growth, branching. continuously twist to show alternating edge-on flat-on views along radii spherulites. Giant screw dislocations bring forth birth new lamellae....
Expression of chirality in the highly ordered assembly structures various types natural and synthetic materials is still a mystery. Although surface stresses have been known to widely exist polymer lamellae, how they affect twisting yet an unsolved issue. Here we report inversion lamellar microbial poly(R-3-hydroxybutyrate) copolymers from left-handed right-handed via copolymerization or blending, with molecular crystalline core unchanged. We interpret observed complicated curvature...
An ATRA based strategy to synthesize vinyl copolymers with monomer-level sequence control is proposed. In each cycle, one allyl alcohol added the ATRP chain end, and then hydroxymethyl residue oxidized carboxylic acid a side group introduced via esterification, making new end active for next cycle.
Imparting repairability to a thermoset coating without compromising other properties is desirable. In this work, catalyst-free and repairable epoxy based on vitrimer chemistry was developed by using mixture of bisphenol A (DER) hyperbranched (HBE) as matrix, succinic anhydride (SA) curing agent. The abundant hydroxyl groups in the HBE accelerate both rates dynamic transesterification. presence DER ensures low viscosity coating, its high value results formation sufficient ester bonds after...
Flexible polymers are widely used in the fields of wearable devices, soft robots, sensors, and other flexible electronics. Combining high strength elasticity, electrical conductivity, self-healability, surface tunable properties one material becomes a challenge for designing polymeric materials these applications, especially Herein, we propose "two birds with stone" strategy to synthesize thermal UV light adaptive polyurethane elastomers high-strength, self-healable, surface-modifiable...
The need for high-performance bioplastics brings new challenges to the design and preparation of next-generation sustainable bioplastics. With emergence a number biobased monomers with similar chemical structure in recent years, it is necessary conduct systematic in-depth study on effects different isomers final material properties. Considering potential barrier bacteriostatic properties emerging thiophene-based polyesters, this work systematically investigated thiophenedicarboxylic acids...
