Abstract
This study begins with a synthesis and characterization of Epoxy/TiO2 composites (Ep–TiO2–Cs) with different TiO2 fillers. The ultrasonic mixing process was employed to disperse the TiO2 fillers into the epoxy resin matrix. The effect of TiO2 contents on microstructural, optical and electrical properties of the Ep–TiO2–Cs have investigated. Several techniques are now being used to characterize the Ep–TiO2–Cs. The microstructure of fracture surfaces was examined by SEM techniques. It revealed that the as-prepared TiO2 particles are a spherical shape structure. At 5.0 wt% TiO2 fillers, it is evident that these spheres are homogeneously distributed in the epoxy matrix. The XRD study confirms that the particle size generally decreases with increasing the added TiO2 fillers in the epoxy matrix. In the UV-light range, the neat epoxy only blocks UV-light in the range of 200–280 nm, it becomes high UV-light blocker (up to 400 nm) via the addition of TiO2 powder with 5.0 wt% fillers. Moreover, the TiO2 content addition obviously enhanced the UV-Shielding efficiency of the epoxy resin.
