摘要: 
相變化材料是一種具有儲能行為的材料,藉由吸放熱的行為可用來控制溫度的改變量。相變化溫控材料的發展主要分相變化材料的選用與改進、相變化材料與基體材料的複合方法、相變化溫控材料的熱傳表現三個方面的內容。透過微粒包覆技術將相變化材料製作成微膠囊相變化材料,提供一種新式材料應用在溫控材料上。本實驗針對微膠囊相變化材料混入基體材料而製備的溫控材料,以掃描式電子顯微鏡觀察複合狀態,並模擬白天升溫或夜間降溫的改變下,依照含量比例、厚度…等變因,觀測其熱傳行為的表現。實驗結果顯示,內含相變化微膠囊的溫控材料能延緩溫度的上升或下降,另外也發現因為微奈米尺度的影響,溫控材料有著不同以往的熱傳行為。

Phase Change Materials (PCM) is a material having energy store capability that can be used for temperature-controlled through absorbing or releasing heat. The study on the development of temperature-controlled material with PCM can be characteristic in the selection of PCM, and improvement of PCM, and the blending methods with the base material with respect to its heat transfer behavior in this study, with the use of cladding technology makes it possible to have PCM manufactured Microencapsulated Phase Change Materials (MPCM). This is a novel properties can be used in the application of temperature-controlled industry and construction. The performance experiments show that the temperature-controlled materials which content MPCM having the ability to delay the temperature arising or dropping form outside, moreover it was found that these temperature-controlled materials having different performance in heat transfer behavior due to the scale effects.
