This review addresses the impact of different nanoadditives on the glass transition temperature (Tg) of polyvinyl chloride (PVC), which is a widely used industrial polymer. The relatively high Tg limits its temperature-dependent applications. The objective of the review is to present the state-of-the-art knowledge on the influence of nanofillers of various origins and dimensions on the …
The last dispersion method was ball milling (Rotate ring mill, Armstec Ind. Co. Ltd., Hwaseong, Korea), dispersed for 4-h in three-steps by controlling each rotating axis speed and time. Subsequently, 10 wt% of PAN was added to the first dispersion to prepare a final composite solution through a co-rotation mixing system.
