本研究的目的在探討ECFA簽定後對MIT服飾產業市場影響，ECFA的簽定，將有助於舒緩台灣紡織服飾業在大陸市場上所面臨的激烈競爭，然而大陸方亦可將服飾產品輸入至我國，這對我國內內需型、競爭力較弱、易受貿易自由化影響之產業將造成相當之衝擊，有鑑於此，政府實施了名為「因應貿易自由化產業調整支援方案」的對應措施，來輔助台灣業者成功轉型成可以自行製造及生產(MIT)，並設計MIT微笑商標給予這些經國家認證的MIT業者來保障他們產品製造的可信度，研究以發放問卷的方式來分析這項政策從2010年施政開始到現今對於台北艋舺服飾商圈的影響。從問卷分析結果得知，顧客普遍認為MIT服飾相較ECFA簽訂前變多了，顧客對於MIT服飾產業的認同提升，也願意出點心力來幫助台灣本土製造的服飾產業，遺憾的是，很多人錯認MIT微笑商標，民眾普遍對MIT微笑商標認知度不足，若提升MIT服飾產品之認知度，MIT服飾產品購買意願就會提升，以達成利用MIT政策來抗衡簽訂…

The purpose of this study is to investigate the ECFA signing of MIT's apparel industry market. ECFA signing will help relieve Taiwan's textile and apparel industry in the competitive China apparel industry market.

In this case, government implementing a policy it is called ”In response to the liberalization of trade in industrial restructuring support programs” to assist them transformation and designing MIT smile trademarks to protect …

高分子PTC材料電阻會隨溫度上升而上升，到了特徵轉變溫度(Tc)電阻值會迅速上升。本研究使用乙烯-醋酸乙烯酯(EVA)為基材，添加竹碳、碳黑粒子及石墨烯為導電填料，製作電阻隨溫度變化材料，探討導電粒子型態對PTC現象與NTC現象產生之因素、基材軟硬及粒子型態對電阻-溫度曲線的影響及SEM觀察比較不同碳材料在EVA樹脂斷面中之外觀、型態差異，最後使用DSC示差掃描量熱儀分析碳材料含量對樹脂熔點之改變，判斷材料熔點與電阻-溫度曲線變化之關係，發現竹碳與碳黑容易形成PTC現象，石墨烯則易形成NTC現象。材料之熔點不隨碳材種類及添加量改變成趨勢性，但會隨VA含量的增加而降低。
