Evaluation of Porosity for Gamma Irradiated Poly (ethylene oxide): A New Approach Using Microscopic Image Aided with Computer Programming

EasyChair Preprint 3017

Abstract

Porous films of Poly(ethylene oxide)(PEO) are synthesized by casting using gamma irradiated:(a)PEO powder (S-series) &(b)PEO- solution (L-series). The experimental pore-size and distribution of the films is studied using BET adsorption and reported as a function of irradiation dose with concentration of 2 and 4 wt.%. A computer program [PROGIMAGE-POR] is reported for determination of porosity and pore-distribution using SEM and correlated with BET. Novelty of PROGIMAGE-POR lies in the exposure of newer pore regime in which experimental pores exists as a part. Theoretical analysis based on aerosity (2D-pores) and porosity (3D-pore) gives an estimate of the tortuous path of void space.
