Reversible addition-fragmentation chain transfer polymerization of chloroprene on the surface of silica nanoparticles was performed to obtain polychloroprene-grafted-silica nanoparticles (PCP-g-SiO2 NPs). These particles were dispersed in a com. polychloroprene matrix to obtain PCP nanocomposites with different silica core loadings (1, 5, 10, and 25 wt%). Two different chain graft densities were studied (“”low,”” 0.022 ch/nm2 and “”high,”” 0.21 ch/nm2) as a function of the grafted polymer mol. mass. The cured samples showed significant improvement in the mech. properties of the PCP rubber nanocomposites as compared to the unfilled PCP as measured by standard tensile and dynamic mech. anal. even with low silica content. The mech. properties of the nanocomposites were notably enhanced when the graft d. was low and grafted mol. masses were high. Transmission electron microscopy (TEM) and Small-Angle X-ray Scattering (SAXS) were used to analyze the dispersion states of the grafted nanoparticles which confirmed the correlation between high grafted chain lengths and improved dispersion states and mech. properties.
