内容記述 | For the quantitative evaluation of gas solubility in polymeric films, the Freeze?Purged-Desorption (FPD) method has been developed. The FPD method consists of three operational periods based on three consecutive stepwise changes in the system temperature,freeze-period (F-period)for the fixation of sorbed gas in the film at the temperature of liquid nitrogen, purge-period(P-period) for the removal of physically adsorbed gas from a sorption chamber wan by a He gas stream at the boiling point of the sorbed gas component, and desorption-period (D-period)for the desorption of sorbed gas from the film at sufficiently higher temperatures than the boiling point of sorbed gas. From the graphical integration of the desorption curves obtained at the D-period,the amount of sorbed gas was evaluated exactly. The temperatures of F-,P- and D-periods could conveniently be varied according to the kinds of sorption gases. The solubility of CO_2 for LDPE,PS and PAN films were evaluated to be 0.310,3.90 and 0.098[cm^3(STP)/ cm^3(atm)]respectively,which were approximately 20-40%higher than the reference values evaluated with barometric techniques. The validity of this method was reconfirmed by good reproducibility of the desorption curves,reconfirming the exact difference from the blank curve obtained with non-porous glass beads. | |||||
