N2 - Liquid Silicone Rubber (LSR) is an elastomer which is widely used in manufacturing industries for variety of applications. LSR has excellent physical and chemical properties which makes it ideal for manufacturing of different components. Plasma treatment of LSR enhances its wettability and adhesivity by converting its hydrophobic surface into hydrophilic one. In this work, nitrogen plasma treatment of the LSR samples were carried out and the changes in the surfaces were observed. The effect of hydrophobic recovery was also studied. Samples were subjected to varying electric current and exposure time in the microwave plasma cleaner. Contact angle measurements before and after the treatment were carried out to analyze the surface changes of the nitrogen plasma treated LSR samples. The droplets of Type II water, tear solution and saline solution were used in this analysis. Clear differences were observed in the samples exposed to different plasma parameters and droplets. Only under moderate current level (10A-27A) short time interval (45-75 sec) hydrophobic recovery of LSR samples was delayed for Type II water and tear solution droplets used in the contact angle measurement. Hence surface properties of LSR can easily be changed and enhanced by nitrogen plasma treatment.
