摘要: 采用溴苯作为高折射率掺杂剂,通过界面凝胶聚合法制备了折射率呈梯度型分布的塑料光纤棒.研究发现,在聚合反应前期,混合物在真空与60~70℃的条件下聚合,而后期反应在高压气氛中进行,可以消除光纤棒中的气泡或真空泡.利用Vrentas-Duda自由体积理论,对梯度型折射率分布的形成进行了分析,建立了物理模型,并进行了模拟分析

Abstract: A gradedient refractive index(GI) polymer rod was prepared by interfacialgel polymerization, in which the polymerization was performed in a PMMA tube and bromobenzene(BB) was used as a higher refractive index molecule. By decreasing the reaction temperature to 60—70 ℃, and in the early stage of the reaction, gas in the reaction mixture under vacuum could be easily overflowing from it, in the later stage, the reaction mixture under a high pressure was compressed and the defects of voids or bubbles of the GIpolymer rod were decreased. By using the new technology, a GIpolymer rod, without any defect of void or bubble, was made. Adetailed mechanism of gradedient refractive index formation was given and simulated according to the Vrentas-Duda free volume theory.

Key words: Gradedient refractive index, Polymer rod, Interfacial-gel polymerization, Simulation
