本研究首先製備出溫感性的空心結構 poly(NAM-MAL)乳膠顆粒， 並將以上所製備的中空乳膠顆粒作為載體，將模擬藥物載入包覆於溫 感性高分子載體中，並將此具有藥物釋放控制功能的溫感活性奈米膠 囊顆粒添加到實際的化粧保養品配方中，並進行各項性質的研究。
實驗主要分三個部份，第一部分先製備具溫感應性的中空乳膠顆 粒，使用 MMG、MAL、NAM 等單體為原料，成功製備中空乳膠顆粒。 研究結果顯示，所製備的中空乳膠顆粒其粒徑及性質穩定，即使將所 製備的中空乳膠顆粒於常溫環境中保存 90 天，中空乳膠顆粒的外觀及 粒徑依然非常穩定無變化。
第二部份研究是利用所製備的空心乳膠顆粒，將模擬藥物包覆於 其空心內殼中，以達到釋放控制的緩釋及長效性能，並利用穿透式電 子顯微鏡(TEM)觀察載藥後的空心乳膠顆粒形態及結構。
最後第三部分，將包覆模擬藥物的溫感中空乳膠顆粒載體添加於 同時具有保養及彩粧功能的 CC 霜中，並分析其各項物化特性。

In this study, a temperature-sensitive hollow structure poly(NAM-MAL) latex particles was prepared. Using the hollow latex particles prepared above as a carrier to load the simulated drug into the temperature-sensitive hollow carrier capsules. These temperature-sensitive active nano capsules with the function of control-release were added to actual cosmetic formulations and properties were studied.
The experiment is mainly included three parts. In the first part, the hol- low latex particles with temperature sensitivity were prepared. The mono- mers of MMG, MAL and NAM were used as raw materials. The hollow latex particles were successfully prepared. The research results showed that the particle size and properties of the prepared hollow latex particles were stable. Even if the prepared hollow latex particles were stored at room temperature for 90 days, the appearance and particle size of the hollow latex particles were still very stable and unchanged.
The second part of the research was to use the prepared hollow latex particles to encapsulate the simulated drug in its hollow inner shell to achieve controlled and long-term release performance. The morphology of hollow latex particles was observed by transmission electron microscopy (TEM).
Finally, in the third part, the temperature-sensitive hollow latex particle carrier coated with the simulated drug was added to the CC cream with both skin-care and make-up functions. Its physicochemical properties were ana- lyzed.
