Plant stem are bundles of cellulose nanofibers with a diameter ranging between
10 to 70
nm and lengths of thousands of nanometers. The mechanical performance of the
cellulose nanofibers is comparable to other engineering materials such as
glass fibers,
carbon fibers etc. In this invention a novel process has been developed to
disperse
cellulosic microfibres and nanofibres in solid phase into a molten plastic
matrix or in a
low viscosity water-based resin system in aqueous phase.
Invention relates to manufacturing Bio-nanocomposites of high performance by
dispersing micro-and nano-cellulosic fibres into plastic matrix using
conventional plastic
processing equipment. This invention also overcomes one unique challenge of
bio-nanocomposite
processing, which is to make them commercially viable by surface
modifying cellulosic micro-and nano-fibres derived from renewable resources.
Les tiges de plantes sont des ensembles de nanofibres de cellulose dun diamètre situé entre 10 et 70 nm et de longueurs de milliers de nanomètres. Le rendement mécanique des nanofibres de cellulose est comparable à celui dautres matériaux dingénierie comme des fibres de verre, des fibres de carbone, etc. Dans la présente invention, un nouveau procédé a été élaboré pour disperser des microfibres et des nanofibres cellulosiques à létat solide dans une matrice de plastique fondu ou dans un système de résine à base deau de faible viscosité en phase aqueuse. Linvention concerne la fabrication de bio-nanocomposites de rendement élevé en dispersant des microfibres et des nanofibres cellulosiques dans une matrice en plastique en utilisant de léquipement de traitement en plastique traditionnel. La présente invention surmonte également un défi unique de la transformation du bio-nanocomposite, qui consiste à les rendre commercialement viables en modifiant la surface de microfibres et de nanofibres dérivées de ressources renouvelables.
