Utilizing the amination and imidization reactions of the anhydride groups, soybean oil was transformed into a water-soluble material, which could be applied in a green, water-based route but become water-resistant again after simple heat treatment.

The synthesis of functional polyesters via ring-opening polymerization of chalcogen-containing bridged bicyclic lactones using alcohol as an initiator and organic base as a catalyst was designed. This polyester exhibits thermal recyclability, good thermostability, controllable hydrophilicity, and a defined glass transition temperature.

PEO/PAA-Dopa/Metal fibers were constructed by the synergy interactions of hydrogen bonds, coordinate bonds and covalent bonds. Compared with hydrogen-bonded PEO/PAA fibers, PEO/PAA-Dopa/Metal fibers show high stiffness, strength and toughness, and quick recovery.

The alternating copolymers of hydroxylvinyl ethers and dialkyl maleates have been synthesized by both conventional radical and RAFT polymerizations. The effects of comonomer structure, comonomer feed ratio and monomer concentration on the alternating copolymerization were investigated in detail.

Exchangeable hydroxyl-ester crosslinks were programmed into biodegradable PLA/PBAT blends by straightforward reactive blending. The resultant vitrimeric PLA/PBAT blends show concurrently and significantly enhanced tensile strength, toughness, and heat resistance due to the greatly improved interfacial adhesion and the network structure. Moreover, the vitrimeic PLA/PBAT blends exhibit good reconfigurable shape memory behavior.

SH-PEG and SH-PEG-SH polymers can form linear and looped conformation on the surface by gold-sulfur bonds, respectively. Refilling short-chain PEGs can be seen clearly to improve protein resistance, and the substrate conformation-dependence occurred during protein adsorption.

Carbon nanofiber materials with special core-shell structure were developed by using bimetallic MOF as precursor, electrospinning, electrodeposition and high temperature carbonization. High performance ORR catalyst containing Fe-N_XC active sites, Co-N_XC active sites and Co nanoparticles co-exists in hollow porous carbon fibers.

The effect of temperature on the evolution of physical structures and chain dynamics of TPU with low hard segment content is studied using DSC, SAXS and Time-domain NMR. The SSA thermal fractionation analysis shows a wide length distribution of MDI-BD hard blocks. Softening of glassy fraction of hard blocks and melting of nanocrystals take place successively during heating. Hard and soft blocks are mixed on the scale above nanometers in the melt.

This work found that α-nucleating agent talc and β-nucleating agent TMB-5 can accelerate the non-isothermal crystallization of polypropylene and change the temperature range of self-nucleation Domain II. In presence of TMB-5, the self-nucleation effect enhanced the formation of α-crystallite.

Boron nitride is chemically modified by polyimide brushes that are grafted on the filler surface. Interfacial compatibility between filler and matrix is greatly improved. Tensile strength of polyimide/boron nitride composite film is up to 80 MPa even at 50 wt% filler content. Both out-of-plane and in-plane thermal conductivity are over 0.8 W/(m·K).

Poly(ether ether ketone) separator for lithium-ion batteries (LIBs) is fabricated through a strategy consisting of coaxial electrospinning, low-temperature treating, shell removal and hot-pressing. The separator exhibits excellent heat-resistance and electrochemical performance, which allows to get LIBs operating over 150 °C.

The Mullins effect is mainly dominated by the natural rubber (NR) matrix and the effect of carbon black (CB) phase is the strain amplification of NR viscoelasticity. Cyclic stretching may lead to the destruction of CB aggregates and the interface between CB and NR segments.

We designed and prepared the ring-shaped zinc coating on carbon fiber surface, which improved the interfacial properties between fibers and the matrix and resulted in the enhanced toughness of the composites. The synergistic effect of porous structure and conductive network caused by ring-shaped zinc decorated carbon fibers in the RPU matrix made the composites exhibited the satisfactory electrical conductivity and EMI shielding properties.

The work involves investigation of synergistic effects of gamma irradiation, tensile stress and absorbed moisture on the radiolysis behaviors of silicone foams by experiments and theoretical simulations. The synergistic effects unveiled by reactive molecular dynamics at the atomic scale are due to the moisture-induced neutralization and stabilization of the macromolecular radicals.
