Autoxidation Induced Metal Nanoparticles Synthesis in Biobased Polymeric Systems: A Sustainable Approach in Hybrid Materials Development
Design and synthesis of organic–inorganic hybrid materials from biobased monomers/polymers have a tremendous impact on industry and the environment. Our earlier successful demonstration of in situ synthesis of metal nanoparticles using various forms of self-assembled organic soft materials such as molecular gels and liquid crystals proved to be an efficient approach in preparing hybrid materials. The present study shows the successful extension of previous strategies to generate metal nanoparticles (MNPs) in polymeric systems, another form of soft matter. We have synthesized a biobased polymer, poly(cardanyl acrylate) (PCA) from cardanol. Autoxidation (cross-linking) of PCA produced various free-radicals which were used as a tool to reduce metal salts to prepare and stabilize the gold and silver nanoparticles in situ. This sustainable approach enabled us to avoid external hazardous reducing and stabilizing agents.

- The goal of the creation of a biobased economy is challenging to agriculture, forestry, academia, government and industry. The extractable resources of the Earth are finite, regardless of the quibble over when they will be depleted. The economic, political and social demands for biobased chemicals, materials and energy are expected to radically transform the materials industries, particularly the plastics industry as well as the biofuel industry. These changes will be based on the principles of sustainability, eco-efficiency, industrial ecology, and green chemistry and engineering. In keeping with the growth of knowledge in this field, there is a strong need for a forum to share original research related to biobased materials and bioenergy. The Journal of Biobased Materials and Bioenergy (JBMB) has been created as an international peer-reviewed periodical to fulfill the need for communication in these research areas. This journal will encompass related research activities in all fields of science, engineering and the life sciences.
