SELF-ORGANIZED POLYMER AGGREGATE WITH A HIERARCHICAL STRUCTURE AND ITS SUPERHYDROPHOBIC EFFECT
Polymer aggregate with a morphology similar to the papilla on lotus leaf was self-organized by adding 16 wt% water into 5 mg/mL polycarbonate solution in N, N-dimethylformamide. The hierarchically structured aggregates at micro- and nano-scale show superhydrophobicity without the need of modification with low surface energy compound. Small amount of liquid can be wrapped by the aggregates to form the so-called liquid marble. 1 Influence of the amount of water added into the solution on the morphology of the resultant polymer aggregate was studied. By using the hierarchical aggregates as the building blocks, superhydrophobic coating with a static water contact angle larger than 160° and sliding angle less than 5° was formed (5 mg water). Other solutions, like acid, basic or blood plasma are also strongly repelled on the coating. 2
