摘要: | 近年,生醫感測技術日益重要,表面電漿共振感測是其中一個重要的技術。我們設計了金奈米雙層週期性遠離式光柵結構,並用有限時域差分法模擬,分析光場在金膜與雙層光柵中的雙重共振現象,以達到比單層光柵更強的耦合,產生更強的表面電漿波。藉由分析光柵的透射與反射光譜設計使入射光的能量達到最大值。產生更強的共振現象,有利於表面電漿共振感測技術,使其靈敏度更高。隨著科技發展,環保意識頭,電動車發展快速。電池為電動車中很重要的一環。高分子固態電極被期待為安全度極高的電池材料。其中聚氧乙烯又是被廣泛的使用。本研究利用分子動力學模擬不同重量百分比的烯參雜石墨烯並探討其的玻璃轉換溫度,楊氏系數,與持續長度,並發現石墨烯重量百分比越多,奈米混合物的楊氏系數,降伏強度,玻璃轉換溫度也越高。幫助於其應用在高分子固態電池薄膜領域之應用。 In recent years, biomedical sensing technology has become increasingly important. One of the most important method of biomedical Sensing technology is the surface plasmon resonance. In this study, the double layer remote-Au-grating system is proposed. By using finite-difference time-domain method and analyzing the double resonance of the light field in the middle of Au film and Au grating and the transmittance and reflectance spectrum, the incident light energy and the surface plasmon polaritons intensity are maximized. It is facilitated to the sensitivity of surface plasmon resonance sensing technology. With the development of science and technology, electric vehicles have developed rapidly. The Li-ion battery is an important part of electric vehicles. Polymer solid-state electrodes are expected to be extremely safe battery materials. Polyoxyethylene is also widely used. In this study, we use the molecular dynamics to simulate polyoxyethylene/graphene with different weight fraction and study the Young's modulus, yield strength, glass transition temperature. We found that when the weight fraction of graphene increase, the Young's modulus, yield strength, glass transition temperature increase, too. It is helpful for its application in the field of polymer solid-state electrodes. |
