Ion beam induced liquid crystal alignment properties of 4-alkylphenoxymethyl-substituted polystyrenes

Liquid crystal alignment behavior on sulfonated poly(arylene ether sulfone) films

“…The water contact angles on the polymer films decreased with an increase in the DS, indicating that the changes in pretilt angle are related to the changes in wettability on the polymer films, as described previously. [20][21][22] The electro-optical performance of the LC cells having the same cell gap of about 4.5 μm was determined by measuring the voltagetransmittance (V-T) and response time values using the same conditions. The V-T curves were almost identical for the two alignment films when 10 V was applied to each cell.…”
