Effect Of Surface

Starch/Styrene Butadiene Rubber (SBR) biocomposites were prepared by directly blending of starch and SBR on a two-roll miller. Two types of starch: pure starch and modified starch (M-starch) were used as rubber fillers. M-starch were synthesized by grafting of methyl methacrylate (MMA) monomer onto starch backbone using ceric ammonium nitrate-initiated radical polymerization. Coupling agent styrene-g-(maleic anhydride) (SMA) was used to further improve the interfacial interaction between the filler and rubber matrix. The morphology and mechanical properties of unmodified starch/SBR and M-starch/SBR biocomposites with SMA content of 0, 1, 3, and 5 phr were investigated. SEM observations showed the particle size of M-starch decreased and their dispersion in the SBR matrix significantly improved than unmodified starch. Mechanical properties of M-starch/SBR biocomposites were superior than those of unmodified starch/SBR biocomposites.

Attapulgite (AT)/natural rubber (NR)/ styrene-butadiene rubber (SBR) nanocomposites have been prepared after attapulgite was modified by different coupling agent. The treatment of AT caused the adhesion between AT nanorods and the nature rubber/styrene-butadiene rubber was improved, which enhanced the tensile properties of the matrix. The tensile strength of composites attained 15.6 MPa after AT was modified by 3%wt Si-69 coupling with addition of 20 phr.
