Technology Introduction:
Our team focuses on developing composite hollow fiber membranes. The inner and outer layer structures were optimized to enhance the gas permeance. In parallel, we developed a continuous wetting/coating process by utilizing the immiscibility of wetting and coating solutions. A Plasma treatment was adopted to improve their interfacial compatibility, and novel selective-layer materials were synthesized and patented to overcome the permeability–selectivity trade-off relationship for CO₂ capture.
Industry Applicability:
The hollow fiber membranes developed by our group provide a high surface area, modularity, and low energy requirement, making them ideal for carbon capture in coal-fired power plants and heavy industries. Their robust structure ensures long-term stability under harsh conditions. This scalable and cost-effective membrane technology can support Taiwan’s transition to have sustainable industries with net-zero emissions.
