石墨烯/聚乳酸導電高分子應用於3D列印電鍍支架之研究

電鍍這項技術，非常廣泛的應用在國內外以及各種產業上，例如增加金屬表面的強度，不管是機械性還是化學性或是物理性，都有顯著的幫助，更可經過特殊的處理來附著在塑膠材料上。一般而言，電鍍過程中都會使用支架來連接鍍件與電極之間，對支架性能的主要要求有足夠的機械強度、導電性能良好、不易腐蝕的材料為主。電鍍中、大型或是量產型的鍍件，都會有支架所吊掛著，來進行電鍍的動作，但對於小批量或是特殊造型的鍍件，就必須另外設計特殊的支架，來符合電鍍的要求，但在這樣特殊要求下設計的支架，有成本的考量以及形狀特殊的加工難度，所以在這些考量下，希望可以尋找出一個能夠排除加工困難和降低成本，以及符合強度好、導電良的方法，來製作電鍍的支架。 3D列印是近幾年各國競相發展的產業，幾乎所有能夠想像的或是之前無法完成的各式各樣的形狀都能夠透過3D列印的方式生產出來，本次實驗，想透過3D列印的方式，設計較小較複雜的支架，在其表面鍍上石墨烯，來增加其機械性質和導電性及抗腐蝕性。石墨烯是近代稱得上偉大的發現，石墨烯（Graphene）是一種碳原子以sp2混成軌域組成的六角型蜂巢晶格平面薄膜，石墨烯實質上是一種透明、良好的導體，也適合用來製造透明觸控螢幕、光板、甚至是太陽能電池。為了成功的獲得石墨烯薄膜，參考了大陸合肥工業大學的一項專利，(電鍍沉積法製備石墨烯膜的方法)。使用甲醇與水在適當的比例下，混合成分散液，將少量的氧化石墨烯加入在其中，成為電鍍需要的電鍍液，正極使用3D列印機所列印的支架，而負極使用不銹鋼片，利用電鍍的原理，將氧化石墨烯附著在試片支架上，進而對於石墨烯鍍層進行實驗與分析。鍍上石墨烯的支架在電阻值的量測，有明顯的降低，觀察表面有明顯的鍍層，至於表面溫度上升的部分有較好的散熱效果，抗腐蝕方面有些微的增強。

Electroplating technology is widely applied in various industries. For example, increasing the strength of metal surfaces, whether mechanical or chemical or physical, can be significantly helped by special processing on plastic materials. In general, a plating rack is used to connect electrode and plating. The main requirements of the performance of the hanger are sufficient mechanical strength, good electrical conductivity and non-corrosive materials. Electroplating large or mass production of plating, there will be hanged hanging rack for electroplating process. For small quantities or special shape plating, a special hanger must be designed to meet the electroplating requirements. But to meet such a special request of designing hanging, there will be a cost concern and difficulties of processing on unique shape occur. For consideration for above two issues, to find a way to proceed on the experiment in order to avoid the production of special shape, cost issue and the requirements of intensity and electric conduction. 3D printing is a competitive industry in recent years. Almost all kinds of shapes imaginable or impossible to be completed before can be produced through 3D printing now. In this experiment, smaller or more complex designed hangers are made through 3D printing and coated with grapheme on the surface to increase its mechanical properties and electrical conductivity and corrosion resistance. Graphene is a great discovery. It is a kind of hexagonal honeycomb lattice plane film composed of sp2 hybrid orbitals. Graphene is essentially a kind of transparent and good conductor. It is suitable to be used for creating a transparent touch screen, light panels, and even solar cells. In order to obtain graphene film successfully, a patent of Hefei University of Technology in China is referred to (a method of preparing graphene film by electroplating deposition method). Using a small amount of graphene oxide mixed with methanol and water at a proper ratio, using a graphene oxide solution as a plating solution, a positive electrode using a 3D printing rack, and a negative electrode using a stainless steel plate, using a plating principle, graphene oxide was coated on a hanger with 3D printing design, and then the graphene coating was tested and analyzed. Plating on the graphene attached to the conductive properties and not much difference in the surface of the apparent coating, as part of the surface temperature rise higher temperature, corrosion resistance slightly enhanced.
