Abstract
Titanium dioxide nano filler (TiO2) with (10 nm) particle size, and (0.5 wt%) was used as a dopant to epoxy type (SR8100), polymer matrix nanocomposite (PMNC) was prepared by hot vibration dispersion, and tested using FTIR, and UV spectra. It has been found that transmission of (PMNC) largely enhanced, and absorption of UV radiation reaches up to (52%) at (500 nm), (50%) at (1000 nm), and never drop to zero.
