Drying of Polymer - Polymer-Solvent Coatings

This book deals with the first experimental study related to polymer-polymer-solvent coatings. Poly(styrene)-poly(methyl methacylate)-tetrahydrofuran coatings, poly(styrene)-poly(methyl methacylate)-toluene coatings, poly(styrene)-poly(methyl methacylate)-ethylbenzene coatings, and poly(styrene)-poly(ethylene glycol)-chlorobenzene coatings are experimentally designed in order to minimize the residual solvent in single and multilayer coatings. The coatings were prepared using the solution casting technique. The depth profiling study has been done using confocal laser Raman spectroscopy in order to determine depth-dependent concentration profiles in various coatings dried under various conditions. The morphological study has been done using scanning electron microscopy in order to check the final structure of the prepared coatings. The prepared coatings were symmetric, asymmetric, and porous in nature.Thermal analysis of prepared coating has been done using differential scanning calorimeter in order to determine the thermal stability and glass transition temperature of the coatings.
