MediShield™ Superhydrophobic Coating

A superhydrophobic coating is a surface treatment that causes water and aqueous fluids to bead up and roll off rather than spreading or adhering. Superhydrophobicity is defined by a water contact angle greater than 150° — the highest tier of water repellency, similar to the lotus leaf effect in nature. In medical device applications, superhydrophobic coatings are used to protect electronics and external device surfaces from moisture contamination, to enable complete fluid evacuation from pump and cartridge components, and to prevent biological fluid adhesion on diagnostic device surfaces. Unlike hydrophilic lubricious coatings that require water to activate, superhydrophobic coatings are effective in both wet and dry environments, actively repelling aqueous fluids on contact.
