Surface Plasmon Imaging of Ultra-thin LB Films Prepared by Photoreactive Poly(vinyl ocatal acetal)s

Abstract

Ultra-thin polymer films prepared by the Langmuir-Blodgett (LB) technique are one of fascinating materials in many fields of applications. Especially, polymer LB films have a lot of advantages as LB materials, for example, fewer pin-hole due to the amorphous character and thinness of each layer due to structural stabilization by the covalent linkage of the hydrophobic units. Furthermore, the chemical structure is easily modified by functional groups, providing various functions to the polymer LB films while keeping the excellent LB characters.
