Plasma polymerization of styrene was used to modify the hydrophilic surfaces of halloysite nanotubes to investigate the reinforcement effect of new hydrophobic surfaces on the dynamic mechanical properties of halloysite-polystyrene nanocomposites at various degrees of loading Pristine and plasma-modified halloysite-polystyrene nanocomposites were synthesized by solution blending and characterized using various techniques The storage moduli and glass transition temperatures of the composites were analyzed using dynamic mechanical thermal analysis It was found that the rubbery moduli increased substantially after plasma coating with styrene due to the compatibility of the new hydrophobic halloysite surfaces with the polystyrene polymer matrix In addition, the rubbery moduli increased with increasing amount of clay The glass transition temperatures of the composites did not change significantly with the amount of clay The strengths of the plasma-modified composites were also compared with those of recently reported halloysite-epoxy resin composites (C) 2010 Society of Chemical Industry
