In situ preparation of silver nanocomposites on cellulosic fibers - Microwave vs. conventional heating

► In situ synthesis of silver nanoparticles on viscose fibers using sulfated chitosan. ► Conventional and microwave heating are applied and compared. ► All fibers exhibited antimicrobial behavior toward Escherichia coli bacteria. ► Microwave treated fibers showed slightly elongated silver nanoparticles. ► Differences in nanoparticle shape are not due to different heating methods.
