Hydrophilic and Antibacterial Coatings

Every invasive operation as inserting polymer tubes into patient’s body (catheterization, intubation), can bring a number of complications: mechanical stress and mucosa damage, inflammation, high risk of bacterial infection, stenosis, peptide adherence and blockage of the device lumen.

To prevent these problems we proposed modification of the surface of commercially available devices (polyurethanes, PVC and silicone tubes) by dip-coating. Described technique also allows incorporation of antimicrobial and anti-inflammatory agents (triclosan, parabens, iodine, dexamethasone etc.).

Obtained hydrogel layer, based on polyurethane (PU) and polyvinylpirrolidone (PVP) interpolymer, becomes extremely hydrophilic and lubricious after wetting with water-based liquid. We also performed a combination of hydrophobic and hydrophilic cellulose coating on PVC tubes.

Changes of the physicochemical properties were clearly seen during tribological tests against tissue (lubricity), and the measurements of the wetting angle (hydrophilicity).

These properties can significantly enhance comfort during handing and decrease peptides and bacteria adhesion.
