Chloroform (Carolina Biological Supply, USA). Clean rectangular glass slides (7. Apparatus Co., Ardmore, PA, USA) and a video recording system. The vertical deflection of the H-PDMS film immersed in water was measured as a function of time using a Foton probe (MTI-computer using a NIDAQ Data Acquisition system (analog to digital data acquisition unit (Model -USB 6003) purchased from National instruments). The turbidity measurements were performed occasionally to test the quality of water using a turbidity meter (Orion AQUAfast AQ3010), Thermo Fisher Scientific, USA). Further analysis of water in which H-PDMS was submerged was carried out using UV-Visible spectrophotometer (ND-ONEC-W4) purchased from Thermo Fisher Scientific, USA. The spin coater used to deposit a primer on the glass slide was purchased from Headway Research Inc. USA.
