    摘要： The invention discloses an aramid fiber electrode and a preparation method thereof. Silver nanoparticles, carbon nanotubes and polypyrrole were sequentially coated on the surface of the aramid fiber by chemical bonding, to prepare an aramid fiber electrode, two aramid fiber electrodes were wound with an electrolyte to obtain an aramid fiber electrochemical capacitor. Compared with the polymer fiber electrochemical capacitor prepared in the prior art, the aramid fiber electrochemical capacitor provided by the present invention has both high specific capacitance, high energy density, high mechanical performance, high stability, good flexibility and wearability. And other characteristics; the preparation method is controllable and suitable for large-scale applications.

    摘要： The present invention discloses a modified bismaleimide resin and preparation method thereof; under conditions of N,N-dimethylformamide serving as a catalyst, biomass-based 2,5-furandicarboxylic acid and thionyl chloride are acylated to obtain 2,5-furan diformyl chloride, which is then dissolved in dichloromethane with a biomass-based eugenol; under tertiary amine conditions an esterification reaction takes place, and a fully biomass-based bis(4-allyl-2-methoxyphenyl)furan-2,5-dicarboxylic acid ester is thus obtained; same is used for preparing a modified bismaleimide resin. The bismaleimide resin prepared by the present invention has excellent thermal properties and rigidity; the preparation method uses 2,5-furandicarboxylic acid from biomass as well as eugenol; the raw materials are green and environmentally friendly and renewable; the invention also has the feature of a simple production process, and has broad prospects for application in such fields as aeronautics and astronautics, electronic information, electrical insulation.

    摘要： This invention provides a scrollable and foldable transparent polysiloxane film and its preparation and self-healing method. 2-Hydroxyethyl disulfide, diisocyanate and alkane chloride were mixed and reacted to get disulfide-containing diisocyanate. α,ω-Aminopropyl terminated polydimethylsiloxane, diisocyanate and alkane chloride were mixed and reacted get linear chain-extended polydimethylsiloxane. Linear chain-extended polydimethylsiloxane, multi-amino terminated hyperbranched polysiloxane, disulfide-containing diisocyanate and alkane chloride were mixed and poured into a mould. After drying, the scrollable and foldable transparent polysiloxane film was obtained. The polysiloxane film described in this invention are constructed by dynamic physical crosslinking induced by hydrogen bond and permanent chemical crosslinking generated by hyperbranched polysiloxane. Hence, the polysiloxane film achieves both high stiffness and toughness. The good self-healing behavior of the polysiloxane films is originated from the temperature controlled dissociation of hydrogen bonds and exchange reaction rate of disulfide bonds.

    摘要： A preparation method of thermadapt shape memory polymers includes: (1) synthesis of pendant hydroxyl groups functionalized epoxy oligomer using epoxy resin and alcohol amine; (2) synthesis of alkoxyl groups terminated silane crosslinking agent by isocyanate silane coupling agent and diamine; (3) crosslinked shape memory polymers were prepared by condensation reaction of pendant hydroxyl groups functionalized epoxy oligomer and alkoxyl groups terminated silane crosslinking agent. The thermadapt shape memory polymers show high glass transition temperatures and high tensile strength. The original shape of thermadapt shape memory polymers can be reconfigured to a new permanent shape as needed, and thus effectively solving the bottleneck problems of reprocessing or reshape in the traditional crosslinked polymers once after molding. The thermadapt shape memory polymers are suitable for smart materials based on shape memory polymers with complex three-dimensional permanent shapes, and showing unfolding or folding behaviors along with convert to three-dimensional structures under heat stimulation.

    摘要： The present invention discloses a biomass-based epoxy resin and preparation method thereof; under conditions of N,N-dimethylformamide as a catalyst, 2,5-furandicarboxylic acid and thionyl chloride are acylated to obtain 2,5-furan diformyl chloride; then it is dissolved with dichloromethane; under tertiary amine conditions an esterification reaction takes place, and bis(4-allyl-2-methoxyphenyl)furan-2,5-dicarboxylic acid ester is thus obtained; by means of meta-chloroperoxybenzoic acid, its unsaturated double bond is epoxidized to obtain a biomass-based epoxy resin. The process of the present invention is simple; the raw materials come from biomass 2,5-furandicarboxylic acid and eugenol; in comparison with bisphenol-A epoxy resin based on petroleum and coal resources, the raw materials are green and renewable, and are advantageous to reducing the consumption of renewable resources with regard to polymeric material. The obtained cured epoxy resin has excellent thermal properties and modulus, and has broad prospects for application.
