Abstract :The aim of this research paper was to investigate the synergetic effect of micro cellulose and multi-walled carbon nanotubes insert ignore into journalissuearticles values(MWCNTs); combination on physicochemical, mechanical and reprocessing performance of Poly insert ignore into journalissuearticles values(Vinyl Alcohol); hybrid composite films. The hybrid composite films production was carried out by the solution casting method, and the reprocessed films were produced using defective insert ignore into journalissuearticles values(torn, faulty); films from primary production by the same method. The combined use of MWCNTs and micro cellulose improved the hydrophobicity approximately 85% in ratio. After the reprocessing, decreased intensities of the peaks in the FTIR and Raman results confirmed the reduced molecular interaction between all components of the hybrid composite film, moreover, SEM and TEM revealed the negative defects such as agglomeration which caused mechanical strength decrease. The tensile strength of PVA hybrid composite films loaded cellulose/MWCNTs, reached 97 MPa strength value and elongation at break decreased to 33% according to the neat PVA film. The study results revealed that hybridization had a remarkable impact on improving characteristic properties of composite films and reprocessing process might have been compatible with solution casting method.
