Effect of adding nz12 and acrylic acid to polypropylene-blend-seaweed residue composites
Mixing conditions have an important influence on filler dispersion and particle size into the polymer composites. In order to improve the interfacial interaction between SR and PP, two different interface modifications were tested: the treatment of filler surface using a coupling agent (zirconate type, NZ12) and the addition of acrylic acid (AA), under the influence of gamma radiation. The incorporation of seaweed residue (SR) produced an increase in thermal stability of PP composites and it was found that SR has a nucleating effect at 20 pph, indicated through an increase in crystallinity. The incorporation of AA and NZ12 in PP-blend-SR composites resulted in an enhancement in polymer-filler interactions. It was found that these agents have a synergistic effect not only in the improvements of mechanical properties but also in the reduction of the degradation induced by gamma rays.
