Abstract

The development of new polymeric materials based on renewable resources using ecologically benign processes (green chemistry) has been motivated by the growing current concern with sustainability. Materials and substances that possess an intrinsic renewable connotation, including cellulose, starch, proteins, oils, sugars and furan derivatives, have received great attention in this context, and vegetable oils stand out for the great potential of application in chemical modification and further polymerization reactions for the development of new materials of interest. Additionally, furan polymers constitute a large family of macromolecular renewable materials that exhibit a vast array of possible applications. The present project aims at preparing original composite materials with high application potentials and totally derived from renewable resources, following a strategy that has a high degree of innovation related to studies described up to the present. The development steps consist, basically, in: (i) employing a cationic mechanism for the polymerization of different unsaturated vegetable oils and mixtures of unsaturated vegetable oils with furfuryl alcohol for the production of crosslinked materials with tuneable properties; (ii) the production of bacterial cellulose and its corresponding nanocrystals; and (iii) the association of both materials for the production of biocomposites. The properties of these materials will then be evaluated using relevant instrumental techniques. It is therefore intended to associate the originality of the vegetable oil/furfuryl alcohol matrix with the excellent mechanical properties presented by bacterial cellulose to prepare original materials entirely based on renewable resources.
