Laser Chip Lithography-Patterned Nanomembranes for Wastewater Treatment

Haiqing Lin Membrane Research Lab

Surface patterned membranes with enhanced antifouling properties

The goal of this project is to develop a portable, low-cost and energy-efficient nanomembrane patterning scheme, using a laser-chip “stamp”, to achieve excellent antifouling properties for wastewater recovery and reuse.

Overview

The laser-mode patterns will be transferred onto polymer surface by near-field enhanced light-matter interaction to create nanopatterns to reduce any favorable interactions between foulants and membrane surface, resulting in enhance antifouling properties. This project is funded by the National Science Foundation.
