近日，復旦大學傳出資訊，該校科研團隊成功研發柔性雙面印製電路板的綠色製造新工藝，人類科技距離可摺疊螢幕又再邁進一步。這一成果將在本屆中國大陆國際工業博覽會上亮相。
印製電子，顧名思義，就是像印刷報紙那樣大批量地印製各種電子元人民幣器件和電子線路。但是，工業上製造印製電路板的導電線路，最常用的是光刻腐蝕法，也叫減成法，這種工藝存在材料消耗高、生工序多、廢液排放大、環保壓力重等問題。此次復旦大學材料科學系楊振國教授領銜的團隊，成功研發“印刷—吸附—催化加成法”，這種新工藝將為綠色、低成本、大規模、卷對卷製造柔性印製電路提供新途徑。
楊教授介紹，柔性印製電路板有多方面的應用。其一是射頻識別，即人們俗稱的電子標籤，如使用高速公路上的不停車電子收費系統所需的感應卡就是一種電子標籤。未來，電子標籤能實現幾米甚至幾十米以外的遠距離識別，將在物流管理、商品防、公共空間內的貴重物品管理、圖書借和品租賃等方面，為人們帶來諸多便利和服務品質的提升。
另一方面，柔性印製電路板應用於有機發光二極體，將使得採用可隨意摺疊、彎卷的柔性螢幕來製造智能手機、筆記型電腦等移動電子設備成為可能。（新聞來源：巨亨網）
