Nanocarbon-induced rapid transformation of polymer surfaces into superhydrophobic surfaces |
| 초록 |
We present a facile method to fabricate the superhydrophobic polymer surfaces by solubility modulation and nanocarbon (NC)-induced crystallization of polycarbonate(PC). This method consists of dipping polymer sheet in partially soluble solvent and coagulation in nonsolvent for several seconds. As nucleation agent in solution crystallization of PC, single-walled carbon nanotubes (SWNTs), multi-walled carbon nanotubes (MWNTs) and graphene sheets were used. The crystalline micro- and nano-structure was rapidly formed by dipping PC sheets in solution containing NCs, followed by immersing in IPA. That structures were dependent on the dimension of NCs. Especially, in MWNT solution, dipping for ten second was enough to create the superhydrophobic surface. The crystallization of PC and incorporation of NCs during this process was demonstrated by Raman spectroscope measurement. |
