Influence of POSS modifier on NLO properties of the hybrid materials
Influence of POSS modifier on NLO properties of the hybrid materials
摘要
Abstract
The nonlinear optical (NLO) active chromophore was prepared by a bridging agent, glycidyl ether(AGE), to connect disperse orange 3 ( DO3 ) and ( γ-Methacrylpropyl ) -silsesquioxane (MP-SSO). A freeradical polymerization was performed to fabricate the methacrylate/Silica hybrid NLO films. Different amounts(5-25 wt% ) of (γ-methacrylpropyl)-polyhedral oligomeric silsesquioxanes (POSS) were added as the modifier to improve the degree of cross-linking, density and structure of the NLO matrix. As a result, the modified material properties including coating transmittance, glass transition temperature ( Tg), absoption spectra before and after poling, Marker stripes, etc. were presented. The hybrid film containing 15 wt% POSS exhibits the highest Tg, nonresonant second-order nonlinearity (d33 = 92 pm/V) and temporal stability among the others.关键词
