Super Plastic Both Attracts and Repels Water

Abstract:
A new, practical method for making surfaces with patterns of areas that strongly attract and strongly repel water could lead to a highly efficient method for capturing clean water. This versatile material could also find uses in fabricating new types of devices for medical tests and chemical synthesis. Robert Cohen, Michael Rubner, and colleagues started by assembling a nano-structured film made of alternating layers of positively and negatively charged polymers and silica nanoparticles.
