Factors affecting the consistency of water vapour permeation through silicone polymeric tubes
Abstract(#br)The permeation tubes were fabricated using polydimethylsiloxane (PDMS) and their permeation behaviour of water vapour was investigated under different experimental conditions. Experimental results showed that the permeation rate through PDMS wall was largely dependent on tube material and temperature. Permeation rate of water through PDMS shows approximately 100 times higher than that of tetrafluoroethylene–hexafluoropropylene copolymer. High concentration of standard water vapour can be made due to their superior permeation rate.
