Facile stearoyl chloride grafted cotton filter fabric and its application in oil-water separation

Fabrication of Sustainable Hydrophobic Cotton Fabrics with Fluorescence-Emitting Performance Using Novel 1,8-Naphthalimide Functional Molecules

“…Additionally, many interests have been paid to fluorescent cotton fabrics in recent years since they have great prospects in providing smart clothing, health monitoring, and anticounterfeiting, where fluorescent pigments, dyes, rare earth materials, and inorganic quantum dots are immobilized on the fabrics. − Nevertheless, modifications to cotton fabrics face problems including inhomogeneous distribution and weak fastness, because most of the agents are unable to be covalently immobilized on the fabrics. − In fact, cotton fabrics with hydrophobicity and fluorescent functions are promising in outdoor fluorescent warning and decorating textiles. However, there are few reports on the synchronous hydrophobic and fluorescent modification of cotton fabrics.…”

Superhydrophobic and superlipophilic LDH flower balls/cellulose membranes for efficient oil–water separation

“…[12][13][14][15][16][17][18][19] Cellulose membranes have attracted much attention as abundant and sustainable resources with the advantages of appropriate pore size, low cost, greenness and suitability for industrial mass production. 20 And the cellulose-based superhydrophobic/superoleophilic membrane shows efficient oil-water separation performance; e.g., Yuan He et al 21 used the abundant hydroxyl groups on the cellulose surface to modify the cellulose membrane in one step by activating stearoyl chloride to obtain a higher water contact angle of 1471, possessing efficient oil-water separation performance and excellent anti-wear properties. Xiao Wang et al 22 reported that a-bromoisobutyryl bromide was simultaneously treated to produce hydrophobic cotton with an atom transfer polymerization (ATRP) starting site, and then an octadecane chain and polymer grafted superhydrophobic cotton were prepared by surface initiated atom transfer radial polymerization (SI-ATRP) of acrylonitrile and styrene.…”
