Thermally Induced Induction Of Shape Memory Polymer Blend Modified

Shape memory polymer(SMP) including solid state shape memory high polymer material and high polymer gelatin system two big kinds. They all belong to the new function high polymer material category, the research area are extremely widespread, also is very active, and in the aerospace, the electric power electrom, the medical service, the packing, domains and so on intelligence control system has the widespread use. At present domestic and foreign the commonly used shape memory polymer has in the medical service: polynorbornene(PNBE), trans-1, 4-polyisoperne(TPI), shape memory polyurethane(SMPU), polylactide(PLA) and polycaprolactore(PLC). They besides have the very good memory property, the fatty group polyester as a result of itself living thing compatibility and may the degradability, thus has the big application prospect in the bio-medical engineering domain. But the above high polymer all has the price as the industrialization product high, some need from the overseas import, the application cost higher shortcoming, therefore has limited it to a certain extent in other domain application.This work draws up from the above SMP the optimal several of materials with the Polyoxymethylene(POM)Acrylonitrile/Vinylethylene/Acrylonitrile-butadiene-styrene(ABS) carries on again using the increase technology altogether mixed modification, use the appropriate craft and the formula, obtains the hot response temperature to be appropriate, a cost lower heat sends the induction shape memory high polymer material.After this completion of work, it may provide one kind of price lowly to have the shape memory function external use orthopedic surgical department, the orthopedics fixed material. This material and the traditional plaster bandage compares, has the disassemblage convenienty, models the shape quickly, the weight light, the ventilation characteristics and so on comfotbale clean heath. Hopes in the orthopedic surgical department, orthopedic domain to obtain the widespread application, also has the vital practical significance regarding the national ecnomy development...
