F. Vasak et Z. Broz, A METHOD FOR DETERMINATION OF GAS-DIFFUSION AND SOLUBILITY COEFFICIENTS IN POLY(VINYLTRIMETHYLSILANE) USING A PERSONAL-COMPUTER, Journal of membrane science, 82(3), 1993, pp. 265-276
A new method has been developed for the determination of the diffusion
and solubility coefficients of a gas in a polymer membrane. It is bas
ed on the measurement of time dependence of the total volume of the ga
s which has permeated the membrane. The collection and processing of e
xperimental data as well as the gas permeation apparatus were controll
ed by a personal computer. The proposed method has been tested for a C
O2-PVTMS [poly (vinyltrimethylsilane)] system. The results obtained we
re compared with the reported data.
