POL-COAT : A new polyimide electrodeposition and coating process for future strategic markets

聚酰亚胺是一种基本的工程塑料，通常是在电子、生物医学、光电子、航空航天、燃料电池、打印和显示器等市场中高温运行、耐腐蚀和耐磨以及超低毒性应用的首选材料。行业趋势要求产品更小、更轻、更灵活、节能和成本效益高。要做到这一点，需要用新的方法生产聚酰亚胺材料，以克服目前工程工艺的限制。我们研究了一种制备精密调谐聚酰亚胺涂层的新工艺。使用一种称为POL涂层的工艺，可以在鳍状、不均匀的表面上控制薄膜涂层。新工艺允许聚酰亚胺形成更精细的精确图案，并可线性控制材料厚度，范围从亚微米到几十微米。这一工艺填补了一个利基市场，而其他聚酰亚胺工艺，如旋涂、气相沉积和层压等则不存在。POL涂层开辟了新的领域，首次实现了聚酰亚胺的电成型，形成了三维微结构。Pol-Coat是造福人类的新一代关键部件的推动者。

Polyimide is a fundamental engineering plastic and commonly the material of choice for applications operating at high temperature, corrosion & abrasion resistant and ultra-low toxicity, in markets such as electronics, biomedical, photonics, aerospace, fuel cells, print & displays. Industry trends dictate smaller, lighter, flexible, energy efficient and cost effective products. To make this happen polyimide materials need to be produced in new ways, to overcome the current engineering process limitations. We have researched a new process for depositing precisely tuned polyimide coatings. Film coatings are controllable on fin, non-uniform surfaces, using a process known as Pol-coat. The new process allows finer precision patterning of polyimide and linearly controlled material thickness from the sub-micron scale up to the tens of microns. The process fills a niche, where other polyimide processes, like spin coating, vapour deposition and lamination don't go. Pol-coat opens up new frontiers by allowing for the first time Electro-forming of polyimides to form three dimensional micro structures. Pol-coat is an enabler for a new generation of key components that will benefit humanity.
