Abstract
Apparatuses and methods are described that involve the deposition of polymer coatings on substrates. The polymer coatings generally comprise an electrically insulating layer and/or a hydrophobic layer. The hydrophobic layer can comprise fused polymer particles have an average primary particle diameter on the nanometer to micrometer scale. The polymer coatings are deposited on substrates using specifically adapted plasma enhanced chemical vapor deposition approaches. The substrates can include computing devices and fabrics.

A method for forming a protective coating on a substrate, the method comprising:
- depositing a collection of polymer particles having an average primary particle diameter of from about 20 nm to about 10 microns on the substrate to form a fused particle layer.
A coating on a substrate, the coating comprising a first polymer layer disposed directly or indirectly on the substrate and a second polymer layer disposed in contact with the first polymer layer, wherein the second polymer layer comprises fused polymer particles having an average primary particle size of from about 200 nm to about 100 microns.
A coating on a substrate, the coating comprising a polymer layer comprising fused polymer particles having an average primary particle size of from about 200 nm to about 100 microns disposed directly or indirectly on the substrate, wherein the contact angle between a water droplet on the surface of the polymer layer the polymer layer has a contact angle of between about 115° to about 150°.
