Study on impact strength and effect of accelerated weather testing on some properties of poeyoxymethylene/silica nanocomposites

Abstract

The impact strength, some properties and morphology of nanocomposites based on polyoxymethylene (POM) and nano-silica (NS) with different content before and after accelerated weather testing are discussed in this paper. The impact strength of all POM/NS nanocomposite samples is larger than that of POM but decreased when the content of NS is more than 0.5 wt.%. The greatest value is 70.43 J/m at 5 wt.% of NS content (POM/0.5NS). The FTIR spectra of POM and POM/NS nanocomposites show the appearance of characteristic peaks of POM and NS in the nanocomposites.
