Preparation of thin films of cellulose acetate-nitrocellulose blend for solid state nuclear track detection using spin coating technique

Abstract

This paper describes preparation of composite thin films of 12 plus or minus 1 micrometer from cellulose acetate (CA) and cellulose acetate (CA) -cellulose nitrate (CN) blend on a polyester support for solid state nuclear track detection (SSNTD) application. Films were prepared using a spin coater and their experimentally observed film thickness was compared with theoretically predicted film thickness using Damon and Meyerhofer equations. Effect of RPM of spin coater on cellulose nitrate and cellulose acetate thin films is reported for the first time. Track detection properties of CA + CN are tested and compared with indigenous CN and imported LR-115 sup(TM) film.
