The improved resistance of PDMS to pressure-induced deformation and chemical solvent swelling for microfluidic devices
We combined and modified previously isolated treatment processes to improve the properties of PDMS. The improved PDMS shows 860% less deformation compared to regular PDMS at same pressure conditions. Chemical swelling is also improved when the PDMS are in contact with toluene. Rhodamine B diffuses into the improved PDMS much less than the regular PDMS.
