3M Canada has been providing science-based products ranging from healthcare and highway safety to officeproducts and adhesives for over 60 years. They are headquartered in London, ON with research, sales andmanufacturing facilities across Canada. 3M Canada would like to incorporate cellulose nanocrystals (CNCs) asa functional filler into their existing conductive gel adhesives used in bioelectrodes. CNCs are non-toxic, rigidrod shaped particles extracted from wood pulp that possess favourable properties to act as stabilizers,thickeners, templates and reinforcing agents. Conductive gel adhesives, such as in 3M Red Dot monitoringelectrode products, are used routinely in hospitals to monitor electrocardiographic function and to provideinformation in support of diagnosis; consistent performance is essential. Adding CNCs to 3M gel adhesives isanticipated to improve water retention to enhance adhesive and mechanical performance at low humidity. Ourpreliminary studies have shown that adding CNCs to hydrogels significantly increases their mechanicalstrength, functionality and water-uptake abilities.The challenge is to increase the moisture retention (and thus the performance lifetime and reproducibility) ofconductive gel adhesives without negatively affecting other gel properties such as electrochemistry,adhesiveness, strength, and elasticity. We will produce and characterize functionalized CNCs and measure thehybrid gel properties as a function of CNC loading and type, including: water retention/swelling, rheology,transparency, adhesive/mechanical testing. We will work with 3M Canada's R&D Centre for application testingand prototyping to ensure the formulations developed are industrially relevant. This research will establish themain benefits of adding CNCs to 3M's gel adhesives and the IP developed will be exploited in Canada. We arecommitted to helping Canada's Forestry sector and this work will be economically significant for Canada byensuring that we remain at the forefront of CNC discoveries and develop new materials that will lead to jobcreation in Canada.

3M加拿大已提供了60多年来的基于科学的产品，从医疗保健和公路安全到Office Products和Office Products and Goodives。他们的总部位于伦敦，并在加拿大各地的研究，销售和制造设施。 3M Canada希望将纤维素纳米晶体（CNC）ASA功能填充物掺入其现有的导电凝胶粘合剂中。 CNC是从木浆中提取的无毒的刚性形状的颗粒，具有有利的特性，可以充当稳定剂，增稠剂，模板和增强剂。导电凝胶粘合剂（例如3M红点监测器产物中）通常在医院中用于监测心电图功能并提供支持诊断的信息；一致的性能至关重要。将CNC添加到3M凝胶粘合剂中，以提高水分retention屈，以提高湿度低的粘合剂和机械性能。我们的预定研究表明，将CNC添加到水凝胶中会显着提高其机械性，功能和水摄取能力。挑战是增加导电性凝胶粘合剂的水分保留（以及性能终生和可重复性），而不会对其他凝胶产生负面影响，而不会对其他凝胶产生负面影响，例如电力，粘合，粘附，粘合性，强度，强度和弹性。我们将产生和表征功能化的CNC，并根据CNC载荷和类型的函数测量杂交凝胶性能，包括：保留/溶胀，流变学，透明度，粘合剂/机械测试。我们将与加拿大3M的申请测试和原型制作中心合作，以确保开发的配方在工业上相关。这项研究将确定将CNC添加到3M凝胶胶粘剂中的好处，并且开发的IP将在加拿大利用。我们陆上有帮助加拿大的林业领域，这项工作对于加拿大而言将在经济上意义，因为我们仍然处于CNC发现的最前沿，并开发了将导致加拿大工作创造的新材料。
