Abstract
Proteins absorb to almost all surfaces during the first few minutes of exposure. Surfaces that show minimal protein absorption are important in many biomedical applications. Moreover, patient discomfort due to poor lubricating action between tissue and various medical devices, especially contact lenses, is a serious medical problem. An effective polymer for protein- resistant surfaces and improved lubrication properties appears to be polyethylene oxide (PEO). Here we report a study of PEO films on low temperature isotropic (LTI) carbon surfaces, including preparation using a photochemical reaction, characterization of the thickness of the PEO layer by ellipsometry and measurement of coefficient of friction with a custom built tribometer.
