摘要：首次采用Co^(60)-γ射线辐照法制备了聚氮酯/聚(苯乙烯-丙烯腈)互穿网络[PU/P(St-An)IPNs],并借助FTIR-PAS,SAXS及电子拉伸机等方法对材料的微相分离及力学性能进行了研究。研究表明,采用Co^(60)-γ辐照技术,可以有效地减小IPN体系的微相分离。丙烯腈含量增加,IPN体系的微相分离程度降低。当PU含量为40％时,IPN体系的微相分离程度最小,互穿程度最大。IPN材料的力学性能呈现出良好的协同效应。
Polyurethane/poly (styrene-acrylonitrile) IPNs [PU/P(St-An) IPNs] were first synthesized using Co60-γ radiation. The microphase separation and mechanical properties have been studied by FTIR-PAS, SAXS and electron tensile testing machine. Co60-γ radiation were effective for decreasing the extent of microphase separation in IPNs. The extent of microphase separation decreased with increasing acrylonitrile content in IPN. The microphase separation degree is maximum at the 40% PU. The mechanical properties of IPNs reflected excellent synergistic behavior.
