Abstract

Biodegradable materials are among the viable strategies used abroad to minimize problems caused by improper disposal of plastic waste. The use of cellulose nanostructures become been highlighted as a reinforcing agent in this type of material due to its intrinsic properties. However, there is still a great need to elucidate its effect on the main properties of bionanocomposites. In this perspective, we intend to carry out research (through a sixty-day internship), in collaboration with the Research Group coordinated by Prof. Dr. Vijaya K. Rangari of Materials Science and Engineering Department, Tuskegee University, Tuskegee (AL, USA). The research group, coordinated by Prof. Rangari, has a great experience in processing and characterization of bionanocomposites. The emphasis is on uniform dispersion, adhesion and compatibilization to produce high-quality bionanocomposites for various application. The materials will be prepared and characterized in Brazil (at the Proponent's Research Laboratory), and Tuskegee University intends to improve the techniques of preparation and characterization of biodegradable nanocomposites. The integration of the Group of Prof. Dr. Vijaya will expand the line of action of the proponent, which has been intensifying in the characterization of nanocellulose using Raman spectroscopy, transmission, and scanning electron microscopy to develop new biomaterials. The aim is to expand the properties of the prepared nanocomposites that have been limited due to the low interfacial interaction. This research intends to carry out a training/specialization in the development and characterization of bionanocomposites with nano-cellulosic reinforcements from agricultural residues. (AU)
