摘要

Use the method solvotu00e9rmico assisted by microwave to obtain cellulose nanocomposites ceramic summary the present invention consists in the crystallization of nanoparticle material ceru00e2micThe surface and in the interior of the cellulose fibres forming organic - inorganic nanocomposites.The crystallization process of the ceramic material for the formation of nanocomposites is carried out through a process known as solvotu00e9rmico assisted by microwave.It consists of the controlled application of electromagnetic radiation so as to produce temperature and pressure in a ceramic precursor solution autoclavada where are immersed cellulose fibres.The differential of the present invention relates to the application of controlled conditions of processing (crystallization and growth of the inorganic component) and its interaction with the cellulose fibres.Without changing the structure or harm their electronic properties and structural, providing effective results with time, energy and temperature reduced.A relatively low cost and reduction in waste production.This makes the production of nano composites, since, usually, the processes of crystallization ceramics occur at elevated temperatures.What prevents the conservation of structure of cellulose fibers with loss of technological properties of the material.The proposed technology enables the creation of new biodegradable organic - inorganic nanocomposites by a method deemed sustainable.That allows to obtain new materials with properties fotocatalu00edticas, offering greater resistance to photodegradation, fire, water, and also provides protection to the micro - organisms.
