We report the immobilization of nickel nanoparticles on the surface of cellulose‐grated reduced graphite oxide sheets (rGO). The decoration of GO with magnetic nickel nanoparticles was conducted in three steps. First, pure graphite oxide (GO) was functionnalized by cellulose. Then, the corresponding material was doped with Ni nanoparticles (NiNPs) using NiCl2.6H2O followed by a chemical reduction in presence of hydrazine. The resulting NiNPs/cellulose‐grafted rGO material with a 20 wt% NiNPs content was found to be nearly ferroramagnetic. POLYM. ENG. SCI., 58:1630–1635, 2018. © 2017 Society of Plastics Engineers

Plastisol is mostly a suspension of PVC particles in a liquid plasticizer that flows as a liquid and can be poured into a heated mold. For PVC plastisol applications, in addition to liquid dispersion performance and postdispersion flocculation resistance, outdoor durability is an important end use requirement. Spectral properties of PVC plastisol-based films with or without additional near infrared (NIR) rays barrier fillers have been investigated. Both spherical and lamellar fillers have been incorporated in PVC plastisol at a weight content of 2% to 10% and results show a high impact on the reflectance in the NIR region and on the transmittance in the visible (Vis) region. Experimental results showed that the incorporation of nacre lamellar-based filler in PVC plastisol did not permit favorably change its spectral properties while TiO 2 -based particles ensured a decrease of the transmittance in the Vis and an increase of the reflectance in the NIR.
