A primary building block lacking for the success wearable intelligent garments is the absence of reliable, low-cost, comfortable to wear, and rugged electrically conducting textile (ECT) that would allow the seamless integration of multiple functionalities. One approach in the development of ECTs uses yarns coated with conducting polymers or carbons. The poor adhesion and stability of these materials prevent them from playing a larger role in the US$ 3 trillion textile industry. A low-cost method to alleviating the above barriers and allowing further market penetration of ECTs must be developed. Reactive inkjet printing (RIJ) invented by the researcher will be utilized to 1) self-assemble conducting PEDOT polymer on woven polyethylene terephthalate (PET) fabrics, and 2) create a greener alternative to nonwoven ECTs based on cross-linking of sustainable materials such as nanocellulose. Using RIJ, efforts will be made to chemically bind the conducting materials on the textile surface. The outcome of this research will be durable and versatile ECTs that are capable of withstanding demanding tasks such as folding, stretching, washing, drying and ironing, and provides a platform for effective integration of various device functionalities. The use of RIJ is advantageous as it is environmentally friendly (due to its use of almost 100 percent of the starting chemicals), requires low power (low carbon footprint) and can deposit and pattern chemicals, simultaneously. HQPs involved in this research program will be rewarded with one-of-a kind interdisciplinary and experiential training that will equip them with a unique set of skills needed to 1) catalyze the growth of new industry in Canada, 2) adapt quickly to the rapid changes in technology, and 3) position them to be highly productive members of our society. The vast sector of the Canadian industry will also benefit greatly from our discoveries, including those working in forest products, medical, chemical, aviation and car industry, building and home decor, furniture, and defense, to name a few.

可穿戴智能服装成功的一个主要组成部分是缺乏可靠、低成本、舒适和坚固耐用的导电纺织品(ECT)，这些纺织品将允许多种功能的无缝集成。一种开发ECTS的方法是使用涂有导电聚合物或碳的纱线。这些材料的粘附性和稳定性较差，阻碍了它们在美国3万亿美元的纺织业中发挥更大作用。必须开发一种低成本的方法来缓解上述障碍，并允许电子烟进一步渗透到市场。研究人员发明的活性喷墨印花(RIJ)将被用于1)在机织聚对苯二甲酸乙二酯(PET)织物上自组装导电PEDOT聚合物，以及2)基于纳米纤维素等可持续材料的交联性创建非织造ECT的更绿色替代品。利用RIJ，将努力将导电材料化学结合在纺织品表面上。这项研究的成果将是耐用和多功能的ECT，能够承受折叠、拉伸、洗涤、烘干和熨烫等苛刻任务，并为有效集成各种设备功能提供平台。RIJ的使用是有利的，因为它对环境友好(因为它使用了几乎100%的起始化学品)，需要低能耗(低碳足迹)，并且可以同时沉积和图案化学品。参与此研究计划的HQP将获得独一无二的跨学科和体验式培训，使他们获得所需的独特技能集，以1)催化加拿大新工业的增长，2)快速适应技术的快速变化，3)使他们成为我们社会中高生产力的成员。加拿大工业的广大部门也将从我们的发现中受益匪浅，包括森林产品、医疗、化工、航空和汽车工业、建筑和家居装饰、家具和国防等领域的工作。
