Interaction of Candidate Cleaning Solutions for Sensitive Equipment Decontamination With Polymeric Materials
Abstract
Chemical-polymer compatibility is an important criterion for the cleaning, decontamination, and extraction of hazardous chemicals from sensitive equipment (electronics, optics, and other advanced polymeric materials). Candidate cleaning fluids for sensitive equipment include fluorocarbons and supercritical fluids. The initial evaluation strategy involves the measurement of the sorption and desorption diffusion coefficients of the candidate cleaning fluid in a spectrum of polymer compositions. The objective was to characterize the complete desorption process by the continuous measurement of the entire diffusion process employing thermogravimetric instrumentation. These measurements and calculations provided an estimated 'time before reuse' after the cleaning process. The continuous measurement of desorption provided the high data density required to calculate a low concentration Fick's Law diffusion coefficient and equation for the extrapolations. The composition spectrum selected contains hydrogen bond donor, hydrogen bond acceptor, dipolar, and non-polar polymer structures; over 15 materials were studied.
