Polyacrylonitrile/Wool Keratin/SiO2/Zeolitic Imidazolate Framework-8 Electrospun Fiber Membrane for Highly Efficient Separation of Oil–Water Emulsions
Source abstract
Abstract
With the rapid development of the chemical industry, oil–water emulsion separation has received increasing attention worldwide. In this study, waste wool was used as the raw material. The ratios of polyacrylonitrile and wool keratin were first adjusted to control the fiber diameter of the membrane. Then, micro-nanostructures were constructed on the membrane surface by adding SiO 2 and zeolitic imidazolate framework-8. The zeolitic imidazolate framework-8 on the fiber surface could absorb tiny oil droplets to achieve efficient separation of oil–water emulsions. The prepared membrane has a high flux (>390 L m −2 h −1 ), high separation efficiency (>95%), good chemical resistance, and reusability. The water contact angle and oil contact angle are 0° and the underwater oil contact angle is 143° of the PAN/wool keratin/SiO 2 /ZIF-8 membrane. This research can be used in the study of fiber membrane and oil–water separation.
