Scalable corrosion resistant coatings for thermal applications
… deposition, as well as organic coatings such as Parylene C have great anti-corrosion performance due to their high dielectric breakdown and low moisture permeability. However, their application to arbitrarily shaped metals is difficult or expensive. Here, we develop a sol-gel solution capable of …

The Fabrication of Integrated Strain Sensors for “Smart” Implants using a Direct Write Additive Manufacturing Approach
… reported novel approach employed a biocompatible parylene C as a dielectric layer between the electric conductive titanium and the strain gauge. Work also showed that parylene C could be used as an encapsulation material over strain gauges fabricated on ceramic without modifying the performance of …

Deposition of colloidal quantum dots by microcontact printing for LED display technology
… of the polydimethylsiloxane (PDMS) stamp with a parylene-C coating, quantum dots solvated in chloroform were successfully inked and stamped onto various substrates, including different molecular organic layers. The ability to control the placement and the pattern of the quantum dots independently …

Flexible and substrate-free optoelectronic devices based on III-V semiconductor nanowires
… films are made by encapsulating the nanowires in Parylene C, which are then be peeled off from the growth substrate, thus retaining the vertical alignment of the nanowires. These thin films are used to fabricate a THz modulator and a solar cell. Single and multi-layer THz modulators are fabricated …
