SOLID PHASE DISPERSION AND PROCESSING OF MICRO-AND NANO-CELLULOSIC FIBRES IN PLASTIC PHASE TO MANUFACTURE BIO-NANOCOMPOSITE PRODUCTS OF COMMERCIAL INTEREST

摘要

Plant stem are bundles of cellulose nanofibers with a diameter ranging between10 to70 nm and lengths of thousands of nanometers. The mechanical performance ofthecellulose nanofibers is comparable to other engineering materials such asglass fibers,carbon fibers etc. In this invention a novel process has been developed todispersecellulosic microfibres and nanofibres in solid phase into a molten plasticmatrix or in alow viscosity water-based resin system in aqueous phase.Invention relates to manufacturing Bio-nanocomposites of high performance bydispersing micro-and nano-cellulosic fibres into plastic matrix unsingconventionalplastic processing equipment. This invention also overcomes one uniquechallenge of bio-nanocomposite processing, which is to make them commerciallyviable by surface modifying cellulosic micro-and nano-fibres derived fromrenewable resources.
