JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract The effect of nanoparticles SiO2, TiO2 and Fe2O3 on the rheological behavior of anionic polyacrylamide and a mixed assembly of polymer and cationic surfactants were measured systematically by shear viscosity and oscillatory testing at different concentration of Nano-materials. The results of shear viscosity measurement indicate that for all of the systems, the shear viscosity increases with the addition of nanoparticles and show shear thinning behavior at low shear rate. In the oscillatory test, all of the systems show elastic behavior, which depend on the concentration of nanoparticles. The storage modulus (G’) and loss modulus (G’’) increased as nanoparticles concentration increase. The core flooding experiment were also done with polymer-surfactant solution in presence and absence of nanoparticles and the obtained result indicates the higher oil recovery in presence of nanomaterials. In enhance oi...

JUNIPER PUBLISHERS- Academic Journal of Polymer Science Abstract In an attempt to comprehend the outdoor application potential of biochar reinforced wood and polypropylene composites, their wettability properties were investigated. The localised water affinity was measured through drop shape analysis in a Goniometer whereas the comprehensive susceptibility towards water was done through a thickness swell test. The results indicate that the addition of 12wt% of wood waste (Pinus radiata) biochar to a wood and polypropylene composite had the highest resistance towards water among the three component composites. In general, the predilection towards water increased with an increase in the amount of biochar in the composites. It is recommended to produce the biochar with low pyrolysis temperature (yielding a more hydrophobic biochar) to develop composites with acceptable water opposing properties.
