项目摘要

This project aims at optimizing and scaling up the electrospinning process to obtain membranes of nanofibersof copolymers to improve the reaction rate of Albarrie super absorbent smart fabrics for high powertransformer secondary oil containment application.In a first phase project, financed by an Engage grant, Prof. Demarquette and her team in collaboration withAlbarrie Ltd. research team obtained several electrospun membranes and tested them for oil retention. Theobtained results indicated three block copolymers as best candidates for oil retention. They also indicated thatthe quantity of copolymers used in the smart fabrics produced by Albarrie Ltd. , could be reduced by 5 folds ifin the form of nanofibers, which would imply a cost reduction for the membranes of 50%. During the firstphase project, the membranes were obtained using a homemade electrospinning machine and the processpresented several limitations: only small membranes with an area of around 10 cm2 could be obtained; arecurrent problem of needle clogging was observed. Furthermore, the process was not optimized in terms ofmembranes geometry and nanofiber size.The present project aims therefore at optimizing and scaling up the spinning process to obtain copolymermembranes of nanofibers to be used in oil retention. The steps of the project are1) Solve the problem of syringe clogging during spinning2) Scale up of the process3) Optimisation of the scaled up processThis project shall ultimately lead to the creation of high-quality manufacturing jobs at Albarrie Ltd. Thisproject will strengthen Canada's position as a leader in oil containment and oil spill response technology andhelp mitigating public concerns over potential environmental risk related to oil production, transportation and

该项目旨在优化和扩大电纺丝过程，以获取共聚物的纳米纤维的膜，以提高Albarrie超级吸收性智能面料的反应速率，用于高动力型二级石油遏制应用。保留。对象的结果表明，三个块共聚物是保留石油的最佳候选者。他们还指出，Albarrie Ltd.生产的智能织物中使用的共聚物数量可以减少5倍，如果纳米纤维的形式，这意味着膜的成本降低了50％。在第一个阶段项目中，使用自制的电纺机器获得了膜，并获得了几个限制：只能获得面积约为10 cm2的小膜；观察到了针头堵塞的问题。此外，该过程并未根据膜几何形状和纳米纤维大小进行优化。因此，目前的项目旨在优化和扩大旋转过程，以获得纳米纤维的共聚物，以用于油保留率。该项目的步骤是1）解决旋转过程中注射器堵塞的问题2）扩展过程3）优化规模的过程最终将导致在Albarrie Ltd创建高质量的制造业工作。TheProject将在加拿大的限制和油性危险中涉及机油的领域中的领导地位，以增强加拿大在加拿大的领导地位，并促进质地危险的领导者，并促进质地危险的公理，并促进了梅蒂加层的梅蒂尔普尔群岛层次涉及的层次，并加强
