项目摘要

Vapor sorption analysis (VSA) is a necessary component to evaluate a material's response to moisture and other solvents. It is a key analytical step to validate advanced materials finding applications in water harvesting, polymer netting, thin films, novel adsorbents, natural fibre systems and thermoplastic composites. Such applications show promise to invert the negative feedback loops characteristic of the water-food-energy nexus. For example, while increases in agricultural yields have in the past come at the expense of greater pesticide runoff and increased energy for pesticide production and deployment, the use of advanced polymer nets can instead reduce water contamination and energy use. However, the development of such novel materials requires appropriate characterization in a laboratory setting. VSA can be accomplished through volumetric and gravimetric approaches, each with their advantages and disadvantages. On top of providing information pertaining to adsorption and desorption of various compounds, VSA also provides insight into total surface area and (through models) pore size distribution. Gravimetric approaches are the most common (despite their very long analysis times), and volumetric systems are essentially nonexistant. Further, despite being more prevalent, gravimetric VSAs are generally unavailable in the Montreal area and have required the applicant, co-applicants and prospective users to rely on extensive travel, sample shipping out-of-province or the deployment of unstandardized, low grade (and low precision) homemade alternatives in order to proceed with their work. These efforts have been further limited to strictly the study of humidity adsorption, as the use of other solvents was not possible on such instruments. The diverse research team assembled represents actors from chemical engineering, mechanical engineering and engineering physics, across 3 universities in Montreal. All have as their core values the training of highly qualified personnel from various backgrounds, aiming first and foremost to contribute value-added personnel with real-world, transferable skills to the Canadian economy. Students are the first deliverable of a university professor, and the acquisition of a VSA instrument will not only advance the high-impact research being undertaken, but also solidify a world-class, multidisciplinary training environment. This instrument will be made widely available to the Montreal academic community, and publicized accordingly on a variety of databases (not the least of which is the CREPEC consortium).
蒸汽吸附分析(VSA)是评估材料对水分和其他溶剂反应的必要组成部分。这是验证先进材料在集水、聚合物网、薄膜、新型吸附剂、天然纤维系统和热塑性复合材料中的应用的关键分析步骤。这类应用有望扭转水-食物-能源关系的负反馈循环特征。例如,虽然过去农业产量的增加是以增加农药径流和增加农药生产和部署的能源为代价的,但使用先进的聚合物网可以减少水污染和能源使用。然而,这种新材料的开发需要在实验室环境中进行适当的表征。VSA可以通过体积法和重力法来实现,每种方法都有其优点和缺点。除了提供与各种化合物的吸附和解吸有关的信息外,VSA还提供了对总表面积和(通过模型)孔径分布的洞察。重力方法是最常见的(尽管它们的分析时间很长),而体积系统基本上不存在。此外,尽管重力vsa更为普遍,但在蒙特利尔地区通常无法获得,并且要求申请人,共同申请人和潜在用户依靠广泛的旅行,将样品运往省外或部署不标准化,低等级(和低精度)的自制替代品,以便继续他们的工作。这些努力进一步严格限于对湿度吸附的研究,因为不可能在这种仪器上使用其他溶剂。来自蒙特利尔三所大学的化学工程、机械工程和工程物理领域的研究人员组成了一个多元化的研究团队。这些学校的核心价值观都是培养来自不同背景的高素质人才,首要目标是为加拿大经济贡献具有现实世界可转移技能的增值人才。学生是大学教授的第一个交付对象,VSA仪器的收购不仅将推进正在进行的高影响力研究,而且还将巩固世界一流的多学科培训环境。该文书将广泛提供给蒙特利尔学术界,并相应地在各种数据库上进行宣传(其中包括CREPEC联盟)。
