biocomposite raw material in the thermochemical process by using an extruder attempt have been made to minimize the molecular thermal stress on the fibers 13 in addition to further minimize the thermal stress drying of the fibers 13 is conducted after wet chemical modification through a dehumidification chamber at low temperature upon completion of the modification of the fibers 13 by the acrylic acid solution the acrylic acid solution is drained from the tank and the cellulosic material cellulose fibers 13 are washed with distilled water in a washing step prior to further processing of the fibers 13 as a result of the treatment steps 22 26 the modification end results for the fibers 13 include optimization of the fiber interface with the polymer matrix which can be utilized to make flexible composite product such as for example a nano sensor for biomedical applications enhancement of the wetting between polymer and fiber stronger bonding between the fibers 13 and the polymer matrix reduction of the moisture absorption by the fibers 13 a reduction in the odor of the fibers 13 in part due to the reduction in moisture absorption and less resistance of the fibers 13 to material flow during processing of a material including the fibers 13 such as the extrusion or molding of the biocomposite material including the fibers 13.
