Application of Low-temperature Plasma on the Surface Modification of Protein Biomaterials

Low temperature plasma is a partial ionized conductive gas containing ion,electon,free adical etc. which has high chemical reactivity. This paper summarized the characters and acting principles as well as the application of low temperature plasma technology on the surface modification of protein biomaterials, and forecasted their applied prospects. Especially it make mention of improved absorption and combination of chrome in leather processing by low temperature plasma on the surface modification of collagen fibrils, that it may come into being a new technology of free-chrome.
