Synthesis, Characterizations and Study of Mechanical Properties for Blended Nanocomposites Biased on New Epoxy Resin

Abstract

This research discloses the development and synthesis of blended nanocomposites filled with titanium dioxide (TiO₂). Hybrid polymer networks (HPNs) based on unsaturated polyester resin (UPR) and epoxy resins were synthesized by reactive blending. The optimum quantity from nano particlesof titanium dioxide was selected and different wt. proportions 1%, 3%, 5%, and 7% ratios of epoxy are mixed with UPR resin. The mechanical properties of the blended nanocomposites were compared with those of the basis material (UPR and 3% TiO₂) and with results of semi-interpenetrating UPR/Epoxy blends (semi-IPNs) for one type of new epoxy (P₂) that were prepared. Epoxy resins show good compatibility with the UPR resin on blending, show improves in mechanical properties and tensile strength values are higher for blended nanocomposites, addition improvement in the impact resistance. Considerable enhancement of tensile strength is noticed at very low loading of Epoxy resin. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were employed to study the thermal properties of the resins. Morphological studies of the blended nanocomposites systems were ascertained using scanning electron microscope (SEM).
