Reactive Inkjet Printing (RIJ) & Controlled Crystallisation

喷墨印刷由于其增材性而成为一种很有吸引力的生产工艺选择。它的特别之处在于它能够精确地将微升墨水放置在衬底上的预定位置，从而产生薄膜、二维图案甚至三维结构。这项研究特别重要的是，喷墨打印可以将不同的材料并排放置，或者一个放在另一个上面。一个合乎逻辑的步骤是结合反应物，这导致了一个新领域的出现：反应性喷墨印刷。这里提出的研究旨在为英国在这一新兴领域建立主导地位。提出的研究的主要目的是：-使用喷墨打印机作为合成工具在原位生成功能材料。在一个单一的工艺步骤中，新的薄膜涂层和纳米结构可以被图像化并集成到电子设备中，如导体、晶体管、传感器、印刷电池或显示器。-使用喷墨印刷控制无机系统的结晶。需要回答的主要问题是：-生产印刷电子器件所涉及的整体能源消耗能否减少？-就地合成材料是否能提高性能？-许多晶体系统已经通过喷墨打印生产出来，但是诸如尺寸和结晶度之类的特性能够被控制吗？

Inkjet printing is an appealing choice of production process on account of its additive nature. Its particular strength is its ability to precisely place pico-litres of ink at predetermined locations on a substrate, which results in thin films, two-dimensional patterns and even three-dimensional structures. Of particular importance to this research is the fact that inkjet printing can place different materials either side by side, or one on top of the other. A logical step is to combine reactants, which has led to the emergence of a new field: reactive inkjet printing. The research proposed here intends to establish a dominant position for the UK in this nascent field.The main aims of the proposed research are:- Generate functional materials in situ using an inkjet printer as a synthesis tool. In a single process step, novel film coatings and nanostructures can be patterned and integrated into electronic devices such as conductors, transistors, sensors, printed batteries or displays. - Control the crystallisation of inorganic systems using inkjet printing.The principle questions to be answered are: - Can the overall energy consumption involved in producing printed electronic devices be reduced?- Are there performance increases to be gained as a consequence of synthesising material in-situ?- Many crystalline systems have been produced by inkjet printing but can properties such as size and degree of crystallinty be controlled?
