Zinc-oxide nanoparticles enhancement

Nanocomposites with zinc oxide nanoparticles based on BPI have been fabricated from zinc oxide nanoparticles that are modified with 3-aminopropyltriethoxylsilane as coupling agent [22]. The zinc oxide nanoparticles effect an enhancement of the thermal stability of nanocomposite in comparison to the neat BPI. [Pg.375]

A polymethyl methaciylate (PMMA)-rutile (Ti02) nanocomposite was successfully obtained and its photochemical behavior was investigated [149]. The results indicated that mtile nanoparticles are able to screen the UV radiation and, thus, the photochemical stability of the materials is higher than that of neat PMMA. But, when zinc oxide (ZnO) was employed in PMMA formulations [10, 150, 151], the resulting nanocomposites showed an enhanced photochemical stability upon UV exposure, even at veiy low contents of ZnO (0.017 wt%), but preserved the high transparency characteristic for PMMA. [Pg.129]
