At ambient atmospheric condition nano copper particles CuNPs were prepared from copper chloride dehydrate precursor in aqueous medium using sodium borohydride ascorbic acid and polyvinyl alcohol PYA of two different molecular weights Mws. The prepared sol has been found to be stable for a couple of weeks when kept in ambient atmospheric condition which was confirmed by ultraviolet-visible absorption spectroscopy.

The impregnation of nanoparticles onto fibers surface has been consistently proven by Fourier transformed infrared spectroscopy X-ray diffraction study field emission scanning electron microscopy and energy dispersive X-ray study. CuNPs coated EFB fibers show the increase in tensile strength 25 and antifungal activity 7 with respect to control fibers. The observed findings strongly suggest that nanoparticles can be effectively used as reinforcing agents in natural fibers to improve their property and durability.

Abstract

At ambient atmospheric condition nano copper particles CuNPs were prepared from copper chloride dehydrate precursor in aqueous medium using sodium borohydride ascorbic acid and polyvinyl alcohol PYA of two different molecular weights Mws. The prepared sol has been found to be stable for a couple of weeks when kept in ambient atmospheric condition which was confirmed by ultraviolet-visible absorption spectroscopy. Transmission electron microscopy shows the spherical morphology of CuNPs with an average size of 3.51.1 nm developed in the sol where PYA of high Mw renders smaller size than that of low Mw. The synthesized CuNPs are applied in oil palm empty fruit bunch EFB fibers via cationization process. The impregnation of nanoparticles onto fibers surface has been consistently proven by Fourier transformed infrared spectroscopy X-ray diffraction study field emission scanning electron microscopy and energy dispersive X-ray study. CuNPs coated EFB fibers show the increase in tensile strength 25 and antifungal activity 7 with respect to control fibers. The observed findings strongly suggest that nanoparticles can be effectively used as reinforcing agents in natural fibers to improve their property and durability.
