- Surface Coating
- Product Detail
- Company Profile
- Well controlled thickness: 1-100 nm
- Well controlled polarity from hydrophobic to hydrophilic
Examples: Polystyrene, a highly hydrophobic surface; Polyacrylamide, a highly hydrophilic surface - Well controlled chemical properties from neutral to ionic
Examples: Polyethylene glycol, a neutral surface; Polymer functionalized with DEAE groups, a weak anionic surface - Well controlled polymer chain density
- Mixed polymer layers；Examples: Hydrophobic and Ionic (-SO3H, or -COOH, or -NR3+, or -NR2), etc.
- Anti-fouling；Protein resistance；Chromatographic separation；Micro-channel separation；Protein array；Membrane separation for biological molecules；Nanoparticle functionalization；Contact lens
Sepax Technologies is a leader in surface chemistry technology. Our technologies on surface synthesis can make the thin films from monolayers to polymer layers with the surface structure well defined and the thickness well controlled. The polarities and the functionalities of the coatings could be readily designed to meet various applications. Sepax offers custom-synthesis of surface coatings for capillary tubes, micro-channels and nano-particles.
