Abstract

The preparation of durable super-hydrophobic cotton fabrics (CFs) poses a significant challenge for oil–water separation, primarily due to nanoparticle loss and the utilization of toxic auxiliaries. This study proposes a sustainable method for creating superhydrophobic CFs. Initially, CFs are treated with a mixture of NaOH and urea at low temperatures to enhance surface roughness while preserving mechanical integrity. Subsequently, hexadecyl trimethoxysilane (HDTMS) and butane tetracarboxylic acid (BTCA) are applied to reduce fiber surface energy. This combined approach results in CFs with outstanding superhydrophobic properties, boasting a water contact angle of up to 155°, surpassing nanoparticle-based surfaces. Furthermore, these fabrics exhibit remarkable mechanical and chemical stability, along with enduring washing durability. Notably, they demonstrate effective self-cleaning abilities in the presence of liquid contaminants and excellent oil/water separation performance with a high separation efficiency. The developed CFs hold promise for diverse applications in both household and industrial settings.

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
