Superhydrophobic Nanocomposites Coating Using Electrospinning Technique on Different Materials

摘要

Superhydrophobic coating were fabricated using electrospinning technique on different substrates (glass, ceramic and metal), polymer solutions of (PS/DMF) and (PMMA/THF) were used in different range of composition for each solutions, also epoxy and nano TiO_2 were used to fabricate nanocomposites. Contact angle, surface tension, viscosity were calculated for all specimens. SEM showed the morphology of the surfaces and show that (20%PS/DMF) has a higher amount of beads attached with nanofibers and the number of these beads increased with increasing the viscosity of the polymer solution (PS/DMF), (20%PS/DMF) owned a larger contact angle about (160.739°) for metal substrate and show a superhydrophobicity for ceramic and glass substrate after coating with (20%PS/DMF/TiO_2). All the results were discussed.
