ION COMPLEX MATERIAL HAVING FUNCTION FOR PREVENTING ADHERENCE TO BIOLOGICAL MATERIAL

摘要

In the present invention, a coating film is formed by a coating-film forming composition being contacted with a base and subsequently being dried. The coating-film forming composition contains a solvent and a copolymer that includes a repeat unit containing an organic group expressed by formula (a) and a repeat unit containing an organic group expressed by formula (b) (in the formula, Ua1 represents a hydrogen atom or an alkali metal atom, and Ub1 and Ub2 each independently represent a hydrogen atom, or a linear or branched alkyl group having 1-5 carbon atoms).
