Self assembled thin films of poly(methyl methacrylate) for gas sensing

Abstract

Poly(methyl methacrylate) polymer is selected to produce a self assembled thin film onto a quartz crystal using self assembly deposition technique. The deposition of this poly(methyl methacrylate) film layer is characterized by UV-Visible spectroscopy and quartz crystal microbalance. These results show a uniform high quality and reproducible poly(methyl methacrylate) thin film produced onto the Quartz Crystal Microbalance substrate. The interaction of this poly(methyl methacrylate) film against volatile organic compounds is investigated using Quartz Crystal Microbalance measurement system. A fast and reversible response to chloroform vapor is observed using self assembled poly(methyl methacrylate) film. Our results show that self assembled poly(methyl methacrylate) film gives a promising result for the chloroform vapor sensing application.
