제목 Fabrication and characterization of hydrogels and aerogels based on agarose
초록 Agarose is a polysaccharide extracted from the marine red algae. In the hot solution state, agarose chains exist in a randomly coiled configuration. On cooling below around 40°C, the coils order to form helices which further aggregate into thick bundles called super helices resulting the formation of stable hydrogels. Most hydrogels that are currently used in medical applications and tissue engineering easily fracture even under mild loading conditions due to their poor mechanical strength. The preparation of network structures stabilized with nano-sized fillers has been an effective approach to increase the mechanical strength of gels. In this study, we prepared agarose hydrogels embedded with various nanofillers such as graphene oxide, carbon nanotubes and nano-clays, etc., which resulted in significant mechanical reinforcement. The influence of the addition of fillers on the compressive strength and rheological properties of agarose hydrogels and foams has been studied.
