摘要

摘 要

環氧樹脂（Epoxy resins）為一應用非常廣泛的合成樹脂，在塗料、電子與半導體等相關產業上都有相當廣泛的應用。其中塗料為一相當重要的民生化工產業，其主要的功能在於保護被塗裝物體的品質，增加美觀、價值感以及延長使用的壽命，因此塗料工業又被稱為美容工業，在食、衣、住、行方面，都有相當程度的應用與貢獻。然而以往欲改變產品的機械特性時，都採用添加無機填充材，甚至導入難燃、耐磨等機能性添加劑，但由於使用的添加劑對環境來說仍具有極大的影響，在加上現今環保意識抬頭，將黏土（Clay）應用在環氧樹脂相關產業上，便具有相當的發展潛力及空間。
在本研究中，所合成之環氧樹脂奈米複合材料(Epoxy Nanocomposite)主要希望應用於塗料方面。利用原位聚合法（in-situ）來製備環氧樹脂奈米複合材料。首先在環氧單體中加入有機黏土（SWN）或是奈米無機粒子（AEROSIL 200）進行充分混合，然後固化反應後得到奈米級的尺度分散的複合材料。當SWN加到環氧單體中，隨著環氧單體進入到黏土層間的量增加，其交聯時所產生之彈力便可將適量黏土的層間完全撐開，達到奈米級分散的複合材料。之後探討其熱性質（DSC、TGA）及機械特性（DMA、Hardness）的改變，進而探討樣品的透光度（UV-Vis）、耐化學藥品性與阻絕特性（wettability、contact angle、GPA）。

Abstract
Epoxy resin is one of the most-used synthetic resins today. There are various application in coating, electronic, semiconductor etc. Among them, coating is the most important application in the people's livelihood chemical products. It’s mainly function is to protect the quality of the coating object, to modified the form of the products and increase its value, and also to increase the object’s life spam. This is why coating is also called cosmetic industry. It has a certain level of applications and contributions in our daily life. However when it comes to the time to change its enginery characteristic in a product, inorganic material is the filling that people use before. Some people would even use the admixture, which is hardly inflammable and wearable. But use of this kind of admixtures gives a great deal of pollution to the environment. Nowadays, protect the environment is one of the most important affair in the world, to add the inorganic clay in the epoxy resin related industry has a great deal of potential.
In this research, the main approach is to synthesize the Epoxy/Clay Nanocomposites on the aspect of coating. ‘In-situ’ is the method to prepare the Epoxy/Clay Nanocomposites. First, give a good mix of SQN and Aerosil 200 in the epoxy monomer. To obtain the nanocomposites material which has nanoscale after the consolidation. When SWN adds into the epoxy monomer and the quantity of epoxy monomer in the clay layer increases in the process, the tension, which created by the association between them, opens up a sufficient gap between the clay layers. This would achieve a compound material. Afterward, we would discuss its changes in DSC, TGA, DMA, and hardness. Further more, to discuss the product’s UV-Vis, chemical resistance, wettability, contact angle, and GPA.
