Abstract

A number of different
nanoscale inclusions including nanoclay, nanotalc, and graphene were
incorporated with polyvinyl chloride (PVC), dispersed in N,N-Dimethylacetmide
(DMAC) and cast in rectangular aluminum (Al) molds prior to the testing. The
fire retardancy, thermal stability, and mechanical properties of the PVC
nanocomposites were determined using the ASTM UL 94 standard, thermogravimetric
analysis (TGA), differential scanning calorimetry (DSC), and microtensile test
units. Surface morphology studies of the resultant materials were also carried
out using scanning electron microscopy (SEM). Test results showed that the fire
retardancy, thermal stability, and mechanical properties of the PVC
nanocomposites were significantly enhanced in the presence of nanoscale
inclusions. Among the inclusions, graphene had the major impact on improving
the physical properties, which may be because of its higher thermal
conductivity, mechanical strength, size, and shape. Polymers have a wide range of
applications in daily life, but they are highly flammable and mechanically not
stable for different applications. This study has shown that the weakness of
the PVC could be significantly enhanced by incorporating nanoscale inclusions
for various industrial purposes.
