摘要：Superhydrophobic polypropylene non-woven fabric (PPNWF) was successfully modified with cyclohexane and n-heptane by a simple, fast and efficient method to increase hydrophobicity of it. This research investigated the effect of the dosages of organic solvent, specific mass of PPNWF, the volume ratio of cyclohexane/n-heptane on the hydrophobic property. The optimum modification conditions were determined by regarding reaction temperature, reaction time, mix ratio of organic solvents, and so on. Under the optimal reaction conditions, the contact angle of treated PPNWF increased from 136° to 151.9°. In addition, the decorated PPNWF was applied to oil/water separation which showed a good separation performance in mixture of trichloro- methane and water. Besides, the superhydrophobic PPNWF was used to vapor entrapment and expressed an excellent performance in water vapor interception.
