概要	Collagen peptide (ColP), which was extracted from fish scale with hot water was mixed with glutaraldehyde(GA) in water in the presence of sodium montmorillonite (MMT), and subsequent heat treatment gave the ColP crosslinked by GA (GA-ColP)/MMT composites. Also, the ColP was chain extended by the use of a water-soluble carbodiimide and 1-hydroxybenzotriazole to give a chain-extended collagen peptide (CE-ColP). The composites based on the CE-ColP and MMT were prepared by solution-casting method. The XRD and TEM analyses revealed that the exfoliated nanocomposites are formed for CE-ColP/MMT, and that the degree of exfoliation decreases with the increasing feed amount of GA for GAColP/MMT. Although GA-ColP/MMT films were very brittle, CE-ColP/MMT films were relatively tough. Storage moduli of the CE-ColP/MMT films were higher than that of CE-ColP film, and increased with increasing inorganic content.
