【Abstract】 In this thesis,the permeability of polymer films(BOPET etc. )has been determined by CS-135 form permeameter,and the effect of detection conditions on the permeability determination has been studied. It has shown that pressure difference and temperature affect permeability determination. The characterization of permeability of gases across polymer films has been discoursed.更多还原
