The prevention of bacterial infection to the surfaces has been recognized to be very important in biomedical and health industries. Fluoropolymers have been known to prevent the bacterial infection because of their low surface energy. In this research, poly(oxyethylene) derivatives with fluoroalkyl side chains were studied for their ability to control the adhesion of bacteria. The polymer surfaces have extremely low surface energies compare to common fluoropolymers because those polymers have strong phase separation in nano-scale between the hydrophilic poly(oxyethylene) backbone and hydrophobic fluoroalkyl side chains. To understand the role of surface energy in the adhesion of bacteria, various species of bacteria were used. Surface analysis techniques such as NEXAFs, XPS, GIXD and contact angle measurement were also conducted to identify the surface properties of the poly(oxyethylene) derivatives. |
