Polycarbonate
is a transparent commercial engineering polymer used for its good properties in
many applications, in particular in smartphone protector screens. The nano
composite material consisting of polycarbonate sheet and nano titanium dioxide
particles has been prepared in the present paper. Using a press technique,
three ratios of TiO2 (0.01-0.03-0.05 g) were used with polycarbonate. Hardness,
impact, FTIR, UV, XRD, DSC, tensile strength, contact angle and smoothness
tests were defined as different mechanical, chemical, thermal, scratch and
morphology tests. The results showed that hardness decreased by about 15% and
impact resistance improved by about 10%. The TiO2 level is rising. FTIR showed
that no new peaks existed and that physical interactions between the nano
filler and the polycarbonate matrix were seen to decrease transparency by about
5% as well. After TiO2 was applied, UV showed the absorption of polycarbonate
by radiation. The DSC showed a decrease in the level of Tg and an increase in
material crystallinity after processing. The contact angle test showed that at
first, wettability increased but started to decrease with the addition of more
TiO2 to the surface. With the addition of TiO2 to polycarbonate sheets, the
surface roughness test and the AFM test indicate a decrease in smoothness.
