Abstract
Composite films of polyvinyl alcohol dispersed in ferroelectric liquid crystal (FLC) matrix are fabricated by using Langmuir–Blodgett technique. Pressure–area isotherms show that the composite system formed well aligned monolayer as compared to undoped FLC. Due to molecular interactions, monolayers and multilayers possess good spreading properties and we are able to transfer them onto solid substrates from air-liquid interface. FTIR spectroscopy was used to examine presence of all transferred functional groups on substrate. X-Ray spectrum indicates that even due to presence of PVA in FLC matrix, smectic layer ordering of FLC molecules remains unaltered. During non-contact mode of atomic force microscopy, dense and well aligned homogenous pattern is observed in scanned images.
