Oil contamination is pressing environmental and natural resource issues. Oil-water separation technology can be used for water purification. Traditional methods are either time consuming or energy intensive. Bioinspired materials with combination of affinity and/or repellence towards oil and water in mesh-based methods have attracted widespread attention in the oil-water separation. Among existing materials, superhydrophobic/superoleophilic materials are prone to contamination by oil. Superhydrophilic/underwater superoleophobic materials can only operate underwater which restricts the practical use. In contrast, superoleophobic/superhydrophilic materials are desirable for oil-water separation. However, traditional mesh-based method cannot be used for separation of emulsions since the dispersed microdroplets can easily pass through the mesh pores. Superhydrophobic/superoleophilic cotton has been used for separation of water-in-oil emulsions. In this study, a facile method to fabricate bioinspired superoleophobic/superhydrophilic cotton was developed. The functionalized cotton exhibits an oil-repellent and water-wetting behavior and is capable of separating both immiscible oil-water mixtures and also oil-in-water emulsions without oil contamination. This developed cotton is of interest for various applications.

The purpose of this study is to compare waterproof cast padding material to standard cotton/poly-cotton cast padding material to the presence or absence of cast sores of the heel.
The purpose of this split-mouth, randomized, controlled trial is to evaluate the retention rates of sealants placed under Isolite vs. cotton roll isolation. This study will also compare th...
A TEXTILE fiber obtained from the pappus (outside the SEEDS) of cotton plant (GOSSYPIUM). Inhalation of cotton fiber dust over a prolonged period can result in BYSSINOSIS.
A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)
A highly-sensitive (in the picomolar range, which is 10,000-fold more sensitive than conventional electrophoresis) and efficient technique that allows separation of PROTEINS; NUCLEIC ACIDS; and CARBOHYDRATES. (Segen, Dictionary of Modern Medicine, 1992)
