The use of copper patination has been growing rapidly over the past decade. Copper has been used for centuries due to its**longevity, durability, practicality and beauty. However, the recent global trend towards eco-friendly resource-efficient buildings has**resulted in a rapidly growing interest in the use of copper as a sustainable construction material and for its antimicrobial properties.**Copper as a construction material is durable, has a long life span, requires little maintenance and is readily reusable or recyclable.**Patination occurs naturally but can be also achieved artificially under controlled conditions in order to both accelerate the aging**process and generate a wider variety of patina colours. In the North America alone, green building materials demand is expected**to increase 11 percent annually to $86.6 billion in 2017 with the exterior productsexpected to be the largest segment. Therefore,**patinated copper products for building applications have a great market opportunity.**At the University of Toronto, we propose to develop a robust process by using environmental friendly chemicals to produce the**appearance of naturally aged copper for building applications. This project integrates leading edge concepts in material science,**chemistry and polymers (as a coating). Our novel copper patination materials will be more economic to use in external and internal**applications. This project will advance the current state of aged copper technology and expand the business offering of our**industry partner. Our novel processes for Copper patination as a green building material will find widespread applications in the**production of aged copper.**

过去十年，铜铜锈的使用量迅速增长。铜因其寿命长、耐用、实用和美观而被使用了几个世纪。然而，最近的全球趋势朝着生态友好型资源节约型建筑发展，** 导致人们对使用铜作为可持续建筑材料及其抗菌性能的兴趣迅速增长。铜作为建筑材料是耐用的，有很长的使用寿命，需要很少的维护，并且很容易重复使用或回收。铜锈是自然发生的，但也可以在受控条件下人工实现，以加速老化过程并产生更广泛的铜锈颜色。仅在北美，预计2017年绿色建材需求 ** 将每年增长11%，达到866亿美元，其中外墙产品预计将成为最大的部分。因此，** 建筑用铜材产品具有很大的市场机会。**在多伦多大学，我们建议开发一种强大的过程，通过使用环境友好的化学品来生产自然老化的铜的外观，用于建筑应用。该项目整合了材料科学、** 化学和聚合物（作为涂层）的前沿概念。我们的新型铜铜锈材料将更经济地用于外部和内部 ** 应用。该项目将推进当前的老铜技术，并扩大我们 ** 行业合作伙伴的业务范围。我们的铜铜锈处理新工艺作为一种绿色建筑材料，将广泛应用于 ** 老化铜的生产。**
