Abstract: An object of the invention is to provide a protein-adsorbing material having both adsorption capacity and high-speed treatment performance applicable to not only analysis use but also industrial use, in balance, and to provide a method for producing the same. The present invention provides a protein-adsorbing material comprising a polymer base-material, a polymer side-chain immobilized to the surface of the polymer base-material and a functional group having protein adsorption ability and immobilized to the polymer side-chain, in which the mass of the polymer side-chain is 5 to 30% relative to the mass of the polymer base-material.

Abstract: The present invention relates to a novel composite material, that is, a prepreg, obtained by bonding a film (1) comprised of an organic polymer having substantially no melting point and having a high modulus of 700 kg/mm.sup.3 or more and a high strength of 35 kg/mm.sup.2 or more and a resin layer (2) and/or fiber-reinforced layer (3), a composite molded body, and a method of manufacturing a composite molded body.The composite molded body obtained by bonding the film (1) and the resin layer (2) of the present invention has superior strength, excellent pliability, and large toughness in all directions. Further, the composite molded body obtained by bonding the film (1) and the fiber-reinforced resin layer (3) has both an extremely large impact resistance which could never be obtained with conventional molded bodies and also a strength and modulus greater than in the past. The molded body can be suitably used for aerospace equipment, sports goods, leisure goods, etc.
