Abstract

The project consists of an investigation of optical sensors. On this project, the main focus was to implement materials that had properties such as thermochromism, piezochromism, and be able to detect volatile organic compounds with a color change response. The materials selected for this project were Cholesteric Liquid Crystals (CLCs) in different combinations and ratios. There were also four different methods using Forcespinning © technology to apply the CLCs into a polymer matrix; these were, In-Solution, Dip Coating, Coaxial Spinning, and Emulsion. The best results were given by Dip Coating, but the method with the best viable solution was Coaxial Spinning though it still needs further optimization.
