Disclosed are methods of preparing antifouling coatings on reverse osmosis membranes with initiated vapor deposition or oxidative vapor deposition. The coatings enhance the stability and lifetime of membranes without sacrificing performance characteristics, such as permeability or salt retention.

Ultrathin, conductive and fouling-resistant zwitterionic polymer films

Described are materials and methods for fabricating low-voltage MHz ion-gel-gated thin film transistor devices using patternable defect-free ionic liquid gels. Ionic liquid gels made by the initiated chemical vapor deposition methods described herein exhibit a capacitance of about 1 &#x3bc;F cmat about 1 MHz, and can be as thin as about 20 nm to about 400 nm.

Vapor-deposited nanoscale ionic liquid gels as gate insulators for low-voltage high-speed thin film transistors

Described herein are facile, one-step initiated plasma enhanced chemical vapor deposition (iPECVD) methods of synthesizing hyper-thin (e.g., sub-100 nm) and flexible metal organic covalent network (MOCN) layers. As an example, the MOCN may be made from zinc tetraphenylporphyrin (ZnTPP) building units. When deposited on a membrane support, the MOCN layers demonstrate gas separation exceeding the upper bounds for multiple gas pairs while reducing the flux as compared to the support alone.
