Abstract

Cellulose particles with widths in the nanometer range are biomaterials with unique potentially useful features. Nowadays, a very great effort is being made to find new isolation and application methodologies of such nanomaterials derived from wood, cotton and agriculture wastes. Depending on the extraction process, micro and nanofibrillated cellulose (MFC, CNF) or nanocrystalline cellulose (CNC) can be obtained. These nanoparticles form gels at very low concentrations in water, having potential application as thickening agent for formulated chemical products. However, studies concerning the thickening effect of nanocellulose in complex fluids containing polymers, surfactants and inorganic particles at high ionic strength are still very scarce in the literature.The aim of this project is to establish a new research line at the Brazilian Nanotechnology Laboratory, intended to study the production and the application of nanocelluloses as rheology modifier for complex fluids. It is proposed to use sugarcane bagasse, the most abundant agro-industrial waste in Brazil, as feedstock in the production of these nanoparticles. All the prepared materials will be characterized by different techniques of transmission electron microscopy (TEM) and of atomic force microscopy (AFM), in addition to chemical characterization by infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Rheological behavior of nanocellulose dispersions will be evaluated in different formulations. (AU)
