Abstract

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.

利用废玻璃制成具有不同微观结构的超亲水性和水下超疏水性薄膜,用于油水分离
传统的油水分离方法存在诸多缺陷,包括去污能力有限、分离不彻底、操作复杂和环境污染等。虽然一些薄膜材料在油水分离过程中得到了广泛应用,但也存在易受污染、成本高昂等难题。在这里,我们以废旧玻璃为原料,通过加入不同的添加剂,制造出了三种不同微观结构的薄膜。以 KOH 为添加剂制备的超亲水薄膜和水下超疏水性薄膜与其他薄膜相比性能优异,分离效率高达 99.97%。同时,该薄膜的制备方法具有成本低、操作简单、绿色环保等特点。因此,该方法有望在油水分离领域得到实际应用。

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.
