Super water-repellent poly(alkylpyrrole) films having environmental stability

We present electrochemical synthesis of super water-repellent poly(alkylpyrrole) films which exhibit excellent environmental stability in terms of contact angle (>150°) for water. The poly(alkylpyrrole) films synthesized under an optimized electrochemical condition consisted of thousands of micro-scaled ‘needles’ which densely aligned by shoulder to shoulder. The surface of the aligned ‘needles’ was analyzed by a box-counting method, to be a fractal structure with a dimension of 2.18.
