概要	Fish gelatin (FG) extracted from sea bream scales was reacted with glycidyl methacrylate(GMA), and the product (FG-GMA) was used for photopolymerization in the presence or absence of imogolite nanofibers in the aqueous solution. The photopolymerization of FG-GMA was achieved successfully by irradiation with UV light to yield translucent composite hydrogels. The concentration of FG-GMA varied from 10 to 30% without imogolite, and that of imogolite varied from 0 to 2%. A microtomed gel sample was observed with a TEM, and imogolite nanofibers were found to be dispersed finely in the gelatin matrix. SEM observation of the lyophilized gel revealed that it had a porous morphology. Mechanical properties of hydrogels were measured by compression tests using a mechanical tester, and viscoelastic properties were measured using a rheometer. The mechanical strength and storage modulus of the hydrogel increased with an increase of imogolite.
