Influence of Rapid Homogeneous Irradiation of Electron Beam with Low Energy (RHIEBL) on Water Absorption into Nylon6

Abstract

In order to evaluate the influence of rapid homogeneous irradiation of electron beam with low potential (RHIEBL) on absorption phenomena of boiled water into nylon6, the absorbed mass of water in nylon6 has been measured. The RHIEBL decreases the saturated mass of water absorption in nylon6 and also decreases the initial absorption rate of water, as well as the absorption mass of water in nylon6 at each treatment time. Since the RHIEBL increases the initial reaction index from 1/2 to 2/3, RHIEBL changes the initial mode of water absorption, as well as decreases the absorbed mass of water. Based on the results of ESR and XPS, the RHIEBL forms dangling bonds and then decreases the electrical polarization of nylon6 molecules, resulting in a decrease of the mass of water absorption into nylon6.
