Abstract
The detailed analysis of particle size distribution is desirable in several technical fields that ma-nipulate granular/particulate materials including size reduction. This article describes the mani-pulation of scanning electron micrographs (SEM) of polyaniline (PANI) salts using ImageJ soft-ware. The PANI salts were prepared by two servable methods i.e. emulsion polymerizations and inverse emulsion polymerizations. 1,2 The effects of these synthesis routs on the particles shape and size distributions of the PANI salts were evaluated. Slight differences in the particle shapes were observed for these PANI salts. The polymer synthesized by inverse emulsion polymerization method showed smaller size than the one prepared by emulsion polymerization method. This type of computer based image processing methods provide better solutions to practical measurement and size distribution analysis as compared to the time consuming and vague manual means.
