Incorporation of MoO3 Nanoparticles Into Polypropylene Fibers via Melt Spinning: Investigation of Mechanical, Thermal, and Chromic Properties

Journal of Applied Polymer Science, EarlyView.
Pure PP and PP/MoO3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO3) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.

Production of Elastomeric Composites With Different Methods of Incorporating of Graphene Nanoplatelets Into SBR Latex

Journal of Applied Polymer Science, EarlyView.
This study explores scalable methods of incorporating graphene nanoplatelets into SBR latex with or without a surfactant, using either powder or a masterbatch. Results show that combining a masterbatch with the surfactant DTAB improves vulcanization speed, mechanical strength, hardness, thermal conductivity, and resistance to aging.
