Disclosed are methods for fabricating supercapacitors (SCs) via vapor printing, specifically oxidative chemical vapor deposition (oCVD). Also disclosed are methods of using the supercapacitors, in particular for energy storage devices and photovoltaics.

Monolithic flexible supercapacitors, methods of making and uses thereof

Disclosed are compositions of electroactive polymers (EAPs) having improved performance stability. In the EAP compositions, a cross-linked polymer is deposited onto the surface of the EAP by vapor-deposition methods. Upon contact with an aqueous solution (e.g., an aqueous electrolyte solution), the vapor-deposited polymeric network becomes a hydrogel that encapsulates the EAPs. By modulating precursors and vapor deposition conditions, the mesh size of the resultant hydrogel coatings can be controlled to accommodate the key species that interact with the EAPs.

Enhancing performance stability of electroactive polymers by vapor-deposited organic networks

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

Presented herein are articles and methods featuring substrates with thin, uniform polymeric films grafted (e.g., covalently bonded) thereupon. The resulting coating provides significant reductions in thermal resistance, drop shedding size, and degradation rate during dropwise condensation of steam compared to existing coatings. Surfaces that promote dropwise shedding of low-surface tension condensates, such as liquid hydrocarbons, are also demonstrated herein.
