Abstract:

Superhydrophobic and superoleophilic PET( polyethyleneterephthalate ) foam was successfully prepared by coating of modified silane solution on the surface of PET foam. To prepare super hydrophobic PET foam , raw PET foam was pretreated by alkali to get affinity of -OH group and coated with modified silane solution .The formation of alkali treatment to get rough morphology and then followed modified with silane solution for superhydrophobicity was confirmed with scanning electron microscopy and investigated  the wetting behavior and absorption capacity of probing liquids on the superhydrophobic foam. The coated foam showed higher water repellent activity and higher absorption capacity of oil than raw PET foam with 156 ^◦C of water contact angle and absorption capacity of three kinds of probing liquids were 2times greater than raw PET foam

Keywords:
