Abstract

Control and Systems Engineering

Condensed Matter Physics

Sum-frequency vibrational spectroscopy is an effective tool for probing polymer surfaces and interfaces. This is demonstrated here by its application on rubbed polymer surfaces. The spectroscopic results show that rubbing preferentially aligns the surface polymer chains along the rubbing direction. The modified polymer surface then acts as a template to align the liquid crystal molecules adsorbed on it.
