Synthesis Of Doping Polystyrene And Polyacrylic Acid Ester Functional Materials

As polystyrene have the advantage of good processing properties and resistance to radiation, this article first researched the chemical doping methods of polystyrene, and then prepared single sulfur doped, double sulfur doped and silicon doping polystyrene, the structure,doping quantity of the polymers were characterized, meanwhile the performance of film formation was also studied. In consequence,a novelsulfur doped and silicon doped polystyrene materials were prepared. Moreover, this article successfully explored sulfur chlorogenic acid ethyl ether and ester, sulfonylureas vinyl silane doped polystyrene chemical methods. These novle doping methods which are feasible , practical, simple and doping uniform can meet the demands of design and dopingquantity,furthermore can meet the challenge of inertial confinement fusion target material.In this article,Polyacrylate biological non-degradable type shape memory polymer materials with modified nano-copper powder,β-cyclodextrins, H silicabeab powder for hard link segments (stationary phase), polyacrylic acid shrink for soft chain section and then cured by ring-Opening reaction of epoxy groups were designed.The influence of hard and soft link segments to shape performance, such as the relationship between different proportion and plastic temperature, setting temperature, response rate, response times, etc were also studied. In order to adjust the plastic temperature to 37℃and setting temperature to 25℃,the ratio of soft link segments and hard link segments were changed. The results showd that the shape memory materials have a good shape memory performance and recover rate . These shape memory materials can be used as a candidate material of biological non-degradation implanted devices.
