项目摘要

The business opportunity that this project addresses is the introduction of universal stain shedding decorative paints to thepremium end of the large volume decorative paint market. To address this business opportunity the project team musttranslate the novel surface science recently shown by UCL (Science 6 March 2015) into commercially realistic materials(Omya) for processing into desirable decorative paints (AkzoNobel) for sale to the end user (UK consumers) at a premium,but realistic, price. The problem faced by AkzoNobel is that even the most durable of decorative paints have a tendency tosuffer from staining from common household stains (coffee, red wine) which leads to customer dissatisfaction if the staincannot easily be removed; even requiring redecoration in the some cases. The intended output of the project will addressthis problem as it will deliver universal stain shedding decorative paints from which all stains are automatically released onthe stimulation of the staining processThere are five innovative aspects to this projecta) Delivery of the superhydrophobic surfaces using cost effective minerals, as opposed to the published route based onexpensive titanium dioxide (TiO2), will be innovative.b) The application and use of mixtures of accurately controlled particle size minerals in main stream decorative paints is notactually practiced and so this would be innovative.c) No cost effective decorative paints are available that have the technical ability to self-shed dirt and stains.d) The concept behind the science of this innovation is practised to some extent in stain resistant fabrics. There would beinnovation in transferring the effects in stain resistant fabrics to decorative paints.e) Decorative paints where stain shedding is the marketing focus have not been brought to the UK (or EU27) marketplaceso this would be a commercial innovation.Given the strong current customer needs for delivery and maintenance of perfect colour in the home(http://www.letscolourproject.com/) the proposed technology from this project would be extremely timely.

该项目所解决的商机是将通用防污装饰涂料引入大批量装饰涂料市场的高端市场。为了抓住这一商机，项目团队必须将伦敦大学学院最近展示的新型表面科学（《科学》，2015 年 3 月 6 日）转化为商业上现实的材料 (Omya)，用于加工成理想的装饰涂料 (阿克苏诺贝尔)，以溢价但现实的价格出售给最终用户（英国消费者）。阿克苏诺贝尔面临的问题是，即使是最耐用的装饰涂料也容易受到常见家庭污渍（咖啡、红酒）的污染，如果污渍无法轻易去除，就会导致客户不满；在某些情况下甚至需要重新装修。该项目的预期成果将解决这个问题，因为它将提供通用的污渍脱落装饰涂料，在染色过程的刺激下，所有污渍都会自动释放出来。该项目有五个创新方面： a) 使用具有成本效益的矿物质提供超疏水表面，而不是基于昂贵的二氧化钛 (TiO2) 的已公布路线，将是创新的。在主流装饰涂料中精确控制颗粒大小的矿物混合物实际上并未得到实践，因此这将是创新。c) 没有具有成本效益的装饰涂料具有自我脱落污垢和污渍的技术能力。d) 这一创新背后的科学概念在某种程度上在防污织物中得到了实践。将防污织物的效果转移到装饰涂料上将会是一项创新。e) 以防污渍脱落为营销重点的装饰涂料尚未被引入英国（或欧盟 27 国）市场，因此这将是一项商业创新。鉴于当前客户对在家中提供和维护完美色彩的强烈需求（http://www.letscolourproject.com/），该项目提出的技术将非常出色及时。
