Journal of Applied Polymer Science 84, No. 11, 13 th June 2002, p.2049-59 MANUFACTURE AND PROPERTIES OF CHITOSAN/N,0-CARBOXYMETHYLATED CHITOSANmSCOSE RAYON ANTIBACTERIAL FIBERS... 

Choi et al. reported y-irradiation-induced preparation of Ag/poly(ester) and Ag/nylon nanocomposites (Choi et al. 2003b). Ag NPs were dispersed into poly(ester) or nylon via condensation of polymerization and those nanocomposites were expected to be used as antibacterial fibers or electromagnetic inference (EMI) shielding materials. Ag NPs existed as aggregates in the poly(ester) matrix, whereas the Ag NPs were dispersed in the nylon matrix.

In recent years, research on polymer-metal nanoeomposites and their properties has attracted considerable attention due to their potential applications in catalysts, electronics and non-linear optics. Polymer-metal composites consist of polymer and metal particles on the surface or interior (core) of the polymer matrix." They exhibit various properties depending on the type of metal and polymer, especially the former. These composites not only combine the advantageous properties of polymers and metals but also exhibit many new characteristics that single-phase materials do not have. Precious metals such as silver and gold have been studied most extensively among polymer-metal nanoeomposites." Many polymer-metal nanoeomposites have been prepared in one step with y-irradiation in an aqueous solution. Choi et al. reported on polyester-silver and nylon-silver nanoeomposites prepared by the dispersion of silver nanoparticles, which were prepared by y-irradiation, on to polyester and nylon during condensation polymerization to obtain antibacterial fibers." It was found that the silver nanoparticles aggregated in the polyester matrix, whereas the silver nanoparticles dramatically dispersed in the nylon matrix.

Natural and synthetic zeolites, a family of aluminosilicates with pores and cavities in the range 0.4-1.5 nm, are well-known heterogeneous catalysts and sorbents. Zeolite-incorporated cellulosic fibers and membranes could be suitable for medical antibacterial materials, deodorizers, absorbent pads, sanitary napkins, gas separators, ion exchangers, and so forth however, the complete and continual use of the whole zeolite surface is not easy in the...
