Most major handheld electronics manufacturers have made their devices water resistant in the last two years, with Apple, Samsung and Sony joining Nokia, Motorola and Huawei in waterproofing smartphones.
There are several innovative application developers now producing protective hydrophobic, superhydrophobic and oleophobic (HSHO) nanocoatings to treat electronic devices, including: cellular phones, smart phones, personal digital assistants (PDAs), music players, cameras, video recorders, computers, tablet computers, batteries, e-readers, radio devices and gaming devices. Electronics is the main current market for HSHO nanocoatings at present and the market will witness increased growth in the next few years.

These coatings provide electronic components with water protection from humidity to full water immersion. can be use.
As well as providing a direct barrier to moisture, these coatings can also incorporate anti-icing, anti-corrosion, anti-fouling, and anti-microbial functionalities. Synthesis and applications techniques vary between application developers.
