主鎖型液晶性分子のSHG発現と電場処理

抄録

Improvement of the efficiency of NLO properties of liquid crystalline main-chain polymers has been studied. The sample polymers are copolymers of 2-hydroxy-6-naphtonic acid (HNA) with 4-hydroxy-benzoic acid (PHB). SHGs for the samples processed by mechanical stretching and for electrically poled samples were compared. Electrical treatments have been done using sandwitch type cell, transversely applied cell, and Corona poling method at the liquid crystalline temperature.
