Superhydrophilic and underwater superoleophobic film with different microstructures from waste glass for oil/water separation
Traditional methods for the separation of oil and water exhibit numerous flaws, including limited decontamination capacity, incomplete separation, complex operation, and environmental pollution. Although some film materials are widely used in the process of separating oil and water, they also present challenges such as susceptibility to contamination and high expenses. Here, three types of films are fabricated using waste glass as the raw material by incorporating diverse additives for achieving distinct microstructures. Different micromorphologies resulted in different film properties, with the superhydrophilic and underwater superoleophobic films prepared with KOH as an additive showing exceptional performance compared to the others, with separation efficiencies is 99.97%. Meanwhile, the preparation method of this film is characterized by low cost, simple operation and green environment. As a result, this has the potential for practical applications in the separation of oil and water.
期刊介绍：
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
