摘　　要：采用旋涂法和ＰＭＭＡ微掺杂克服了膜层中的微晶现象，制备了质量较高的尿烷取代聚二乙炔（ｐｏｌｙ－４ＢＣＭＵ）薄膜，膜厚１．２μｍ，采用８ｎｓ脉冲激光测试了其全光开关特性，开关时间分别为１０ｎｓ和３６ｎｓ。High optical quality film of polydiacetylene substituted by urethylane was fabricated with PMMA doping and by spin-coating method and its optical switching property was measured. The switch-on time and switch off time of the optical switch are 10ns and 36ns, respectively.
