  • Publication number: 20220211899
    Abstract: The present invention provides a biocompatible material improved in biocompatibility owing to adsorption of a peptide that has high adhesion with a resin and hardly separates from a surface of the resin, and a functional material including the biocompatible material. The biocompatible material includes a resin and a peptide adsorbed on the resin. The resin has methoxycarbonyl groups and methyl groups, and tryptophan or arginine accounts for 70% or more of amino acid residues in the peptide. As an alternative, the resin is a fluorinated resin, and 2,3,4,5,6-pentafluoro-phenylalanine, 3-(trifluoromethyl)alanine, serine, threonine, histidine, aspartic acid, glutamic acid, phenylalanine, or aspartic acid accounts for 40% or more of the amino acid residues in the peptide. The functional material includes the biocompatible material, and a functional substance. The functional substance is held on a surface of the biocompatible material or is released from the surface of the biocompatible material.

  • Patent number: 9735429
    Abstract: A lithium ion secondary battery includes a binder that binds an active material to a current collector in the positive electrode or negative electrodes or both. The binder contains a base material including a resin having a benzene ring, and a polyacene additive selected from the group consisting of naphthalene, anthracene, tetracene, and derivatives thereof. The active material is a carbonaceous material or a lithium-containing composite oxide having a crystal structure in which a distance between nearest oxygen atoms is 0.19 to 0.29 nm. Adhesion of the binder to the active material during the manufacturing of the lithium ion secondary battery is led to a closest-packed crystal plane in the crystal structure of the active material, so that inhibition of moving of lithium ions in and out of the active material due to the binder may be reduced.
