Abstract

Bio-inspired material systems derived from living organisms constitutes systems fromnature, in form of composites, with molecular-scale interactions optimized to direct functionalfeatures. This project focus on the development of new composite materials based in twonatural polymers, endowed with different properties, microfibrillated cellulose and peptidesfrom mussels. The main properties of cellulose for this work are the high hydrophilicity andmechanical strength and the peptides, namely, have a high adhesion capacity, even underwater.The properties of the new biomaterial are based on the association of chemical structure andmorphology of both cellulose and peptides, such as biocompatibility, biodegradability,hidrophilicity and specially, high adhesion power, even underwater, which can be used in largerange of applications as an alternative to the adhesive in the market.Key words: microfibrilated cellulose (MFC), peptide, adhesion, hidrophilicity (AU)
