An object of the present invention is to provide a complex material in which an ion conduction film is curved and deformed when a potential difference is applied, which is operated at small electric power, has a large deformation amount, quick response performances, large degree of freedom in shape, and is easy in control of deformation, while having strength and durability necessary for practical use and being excellent in an economical aspect. A conductive cloth (preferably having stretchability), which is made conductive through plating of metal on a cloth or metal complex implantation, is joined as an electrode to both surfaces of the ion conduction film (the film in which an ion exchange film or ion liquid is immersed) made of a fluororesin and the like. When the potential difference is applied, the ion conduction film is deformed.

Complex material

This invention relates to a composition useful as an antioxidant or an inhibitor for tyrosinase activity which comprises as an active ingredient a sufficient amount of sericin to exert an antioxidizing ability or an inhibiting action on tyrosinase activity and this composition is applicable as an antioxidant or a tyrosinase activity inhibitor in the field of medicines, quasi-drugs, medicines for external use, cosmetics, foods, food additives or the like.

Use of sericin as antioxidants and tyrosinase inhibitors

Functional fiber products are provided. The functional fiber products are those adhered thereto a protein containing 20% to 40% by weight of serine as an amino acid component and those adhered thereto sericin and deacetylated chitin.
