We are offering polypropylene nano composites. Fabrication of exfoliated graphene-based polypropylene nano composites with enhanced mechanical and thermal properties.
Despite the great potential of graphene as the nanofiller, to achieve homogeneous dispersion remains the key challenge for effectively reinforcing the polymer. Here, we report an eco-friendly strategy for fabricating the polymer nano composites with well-dispersed graphene sheets in the polymer matrix via first coating graphene using polypropylene (pp) latex and then melt-blending the coated graphene with pp matrix. A ∼75% increase in yield strength and a ∼74% increase in the young’s modulus of pp are achieved by addition of only 0.42 vol% of graphene due to the effective external load transfer. The glass transition temperature of pp is enhanced by ∼2.5 °c by incorporating only 0.041 vol% graphene. The thermal oxidative stability of pp is also remarkably improved with the addition of graphene, for example, compared with neat pp, the initial degradation temperature is enhanced by 26 °c at only 0.42 vol% of graphene loading.
