Electrospinning is a fiber formation technique used to generate fibers with diameters ranging from 20 nm to 10 µm. It has become popular in the industrial community as it is a single step process capable to use materials like polymers, metals, ceramics, and other additives. The capability to fine tune sample microstructures and overall physical and chemical properties opens up the possibilities to be used in different applications including medical devices, drug delivery, energy storage, tissue engineering and filtration.
In this presentation we will be showcasing the key aspects of electrospinning, how a solution can be scaled up from one needle to more than 100 simultaneous needles to increase sample throughput and process production efficiency. Key aspects including electrical field, quantity of needles and homogeneity of sample. We will also highlight the importance of why controlling the environmental conditions are crucial when scaling up an electrospinning process. An example on the scale up process will be demonstrated with polyacrylonitrile (PAN) as it is commonly used for hot air filtration and energy storage applications.
