Abstract
Since the dissolution of polyolefins is a chronic problem melt processing has been tacitly accepted as an obligation In this work polypropylene PP was modified on molecular level incorporating polyethylene glycol PEG as graft segment PPgPEG in a range of 6 to 9 mol Gold nanoparticles were nucleated in the presence of the copolymer chains via redox reaction The dissolution of the amphiphilic combtype graft copolymers containing gold nanoparticles 80 nm in diameter was achieved in toluene and successfully electrospun from its solution The diameter of composite fibers was in the range from 03 to 25 μm The design of the structurally organized copolymer fiber mats provided a support medium for the nanoparticles enhancing the active surface area for the catalytic applications The resulting composite fibers exhibited rapid catalytic reduction of methylene blue MB dye in the presence of sodium borohydride NaBH4 compared to corresponding composite cast film
