发布时间：2022-09-06 - 摘要：Recent years water contamination by oil and oil spill in sea are the major disasters impacting the living conditions of human beings and marine environments. Phase selective gelators are providing novel choices for oil spill remediation due to their properties of simple synthesis, environmental compatibility, efficiency and reusability. In this review, firstly, classification and self-assembly mechanism of the phase selective gelators were presented. Secondly, the development of phase selective gelators composed of low-weight molecules such as amino acids, organic acids and salts, steroids and carbohydrate moieties was mainly discussed and organic polymer gelators were briefly introduced. Finally, future development of phase selective gelators was predicted.关键词：Gelator;Phase selective;Gelation;Oil spill

发布时间：2022-09-06 - 摘要：Attractive features of radical polymerization (RP) in the presence of sulfonyl chloride include mild reaction condition, simple system composition, and great monomer versatility. This paper summarized the application of sulfonyl chloride in radical polymerization, including the initiator of atom transfer radical polymerization (ATRP), the initiator of single-electron transfer living radical polymerization (SET-LRP) and the chain transfer agent (CTA) of conversional radical polymerization. This paper gave a general overview about the applicability to different monomers for various applications, the relationship of reactivity with the structure of sulfonyl chloride and the polymer synthesis based on sulfonyl chloride (multisulfonyl chloride initiator and chain transfer monomer).关键词：Sulfonyl chlorides;Initiator;Chain transfer agent (CTA);Atom transfer radical polymerization (ATRP);Single-electron transfer living radical polymerization (SET-LRP);Radical polymerization

发布时间：2022-09-06 - 摘要：Polyimide has excellent resistance to high temperature, but poor fusion and processing properties limited its wide application. Thermoplastic polyimide synthesized by introducing flexible groups, by designing the molecular structure of isomerization and other methods will get improved processing properties, and it can be used for extrusion and injection molding processing directly. In this paper, the synthesis methods of thermoplastic polyimide resin and its monomer were summarized. Moreover preparation methods and performance properties of nylon, poly(ether ether ketone) and epoxy resin modified with polyimide were proposed. Furthermore, the future development of polyimide modified engineering plastics were prospected.关键词：Thermoplastic;Polyimide;Modification;Nylon;Poly(ether ether ketone);Epoxy resin

发布时间：2022-09-06 - 摘要：This review focuses on recent progress of self-healing polymer hydrogel. The strategies targeting self-healing polymer hydrogel, the self-healing contributions from different types of polymers, the self-healing degree of hydrogel and its verification methods were analyzed and compared. Overall, both in the molecular design of self-healing polymer and in the healing mechanism of hydrogels, new and important progress has been achieved. However, the polymer hydrogel’s self-healing ability need to be further improved. The design of novel polymer, the improvement in the fabrication method of hydrogel and the enhancement in self-healing efficiency will have a significant impact on the further application of self-healing polymer hydrogel.关键词：Polymer;Self-healing;Hydrogel;Synthesis

发布时间：2022-09-06 - 摘要：As there is often a certain deviation between actual process conditions and the ideal conditions, after shaping the product there are usually some unavoidable defects, and the residual stress is the most common one. Residual stresses of injection products are the still remained inner stresses even though the outer restrictions have been removed, easily causing warpage, deformation or even crack that will mainly do harm to the parts in many cases when the products get used. So it is important to pay attention to the influence of residual stresses when designing plastic products. This article is mainly to give a relatively detailed introduction to residual stresses, surrounding by their generating, measuring, and decreasing as well as computer simulating.关键词：Residual stress;Measurement of residual stress;Moldflow

发布时间：2022-09-06 - 摘要：Taking octadecane/poly (styrene-methyl methacrylate) (P (St-MMA)) microcapsule as phase change materials, silicone rubber as carrier, octadecane/P (St-MMA)/silicone rubber composites were prepared. The join way and the addition of microcapsule, silicone rubber coated method were studied. The structure and morphology of the composite materials were study by infrared spectrum (IR) and scanning electron microscopy (SEM). Through mechanical properties test such as tensile strength, elongation at break, determine the best processing method. The thermal properties of the composite were studied by thermogravimetric analysis (TG), differential scanning calorimetry (DSC) and thermal storage properties. Results showed that thermal and mechanical properties of octadecane/P(MMA-St) microcapsules/silicone rubber are good when the octadecane made microcapsules is added into the silicone rubber, and the amount of microcapsules is 2 phr (per hundred rubber), the mechanical properties of composites by room-temperature silicone rubber coated microcapsule are superior to those of direct hot curing after blending and hot curing after mixed daub. The enthalpy value of octadecane/P (St-MMA)/silicone rubber composites is 67.6 J/g, the energy storage effect is good.关键词：Composite materials;Silicone Rubber;Energy storage microcapsule;Thermal properties
