The effects of 1, 2, 3, 4, and 5wt% of TiO2 disperse nanofiller on mechanical properties of polyamide hexaglycol (PAHG) were investigated. Specimen was prepared by the hot vibration dispersion technique to make a PMNC. Hardness, tensile strength, ultimate tensile strength, young modulus, and impact at room temperature were tested. It has been found that enhancement in these properties starts at extra low weight percent (1wt%) nTiO₂. The maximum effect of nano TiO₂ addition was on tensile strength, and the lowest was on young modulus.

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.
