Abstract: The adsorption behavior of protein，such as the rate，amount，and the orientation and conformation variation of protein adsorption，largely depends on the chemical compositions of support surface. Regulation of the chemical composition of support surfaces is one important method to control the adsorption behavior of protein. This paper is mainly to summarize the effects of different chemical composition on protein adsorption behavior. The effects of functional groups，including hydrophobic groups (methyl and fluoride) and hydrophilic groups (hydroxyl，carboxyl and amino)，were presented. In addition，it is one commonly used method to graft polymer chains on the support surfaces. The paper is focused on the species，length，density and shapes of grafted polymer chains on the protein adsorption behavior while grafting diverse polymer chains.
