Filler-reinforced
polymer composites have attracted considerable attention due to their enhanced
properties.However,the tensile and impact strength of these composites is weak due to the
difference in surface energy between the inorganic fillers and polymer
matrix.Therefore,improving the interfacial adhesion between the inorganic particles and
the polymer matrix by modifying the filler surface becomes inevitable in toughening the
composites.Recently,some new approaches,have been developed for particulate surface
treatment to produce high performance PRPC[1,2].In this paper,the in-situ polymerization
of butyl acrylate (BA) on the surface of the micro-sized talc was performed by using the
batch seed emulsion polymerization.The treated talc was subsequently used to fill
polypropylene(PP).It is expected that the PBA covered on the surface of talc can improve
the mechanical properties of the PP-matrix composites. |
