摘要

微粒二氧化鈦可以提供防曬製品更優良的散射作用而對紫外線有寬廣保護性，為方便檢视包覆聚合膠體在防曬能力上的影響。我們以體外試驗法比較有無包覆的微粒的二氧化鈦産品。本研究主要探討水溶性聚乙烯吡咯烷酮包覆微粒二氧化鈦粉劑之制備的可能及其防曬特性，藉由不同的二氧化鈦原料以獲知有有效吸收度、粒徑興防曬係數上的改良效果。結果發現包覆聚合膠體可使防曬製品聽有效吸收度更佳，而此包覆膜也不會影響到微粒二氧化鈦的粒徑，並且有極佳的透明度和觸感。

Titanium Dioxide (TiO2) nanoparticle in sun product can provide for excellent scattering and wide protection. Whether TiO2 nanoparticle coated polymer, the influence upon the sun protection efficiency can be determined in vitro. In this research, TiO2 nanoparticle coated polyvinyl pyrrolidone (PVP) is prepared and its sun protection is characterized. By using TiO2 raw materials from different source, the improvement in UV-absorption, particle size and SPF value is obtained. We find that polyrner-TiO2 nanoparticle has better UV-absorption for sun product, and that polymer membrane does not influence its particle size. This polymer-TiO2 nanoparticle has extremely good transparency and sense of touch.
