The authors describe a synthesis method for a series of pulverized expandable graphite (pEG)/melamine-formaldehyde (MF) resin core-shell structure particles. The particles are also added into rigid polyurethane foams (RPUF) to characterize the flame-retardant, mechanical, and thermal insulation properties of the RPUF/pEG-MF composites. It was found that the pEG/MF particles showed good flame-retardant performance in the composites by providing a physical barrier effect....
Conductive polymer composites (CPCs) contain high concentrations of carbon nanotubes (CNTs) to maximize electrical conductivity. However, high nanoparticle concentrations degrade other important properties of CPCs. This study produced CPCs using ultrahigh molecular weight polyethylene (UHMWPE) fillers in place of CNTs in an attempt to maintain important physical and mechanical properties. A thermal analyzer measured the thermal conductivity of the CPC samples using the transient plane source (TPS) method. Results showed ...
