Surface modification and coating technologies are widely used to augment product surface function and to improve performance. With advances in materials and processes, surface technology plays a crucial role in realising new engineering breakthroughs or performance enhancement in various fields.

More Details

A number of different approaches have been used to fabricate nanocoatings including vapour deposition, chemical reduction, pulsed laser deposition, mechanical milling, and electrochemical deposition. Among these processes, the sol-gel process, being able to be carried out in solution, is viewed as one of the most attractive. The sol-gel method is a chemical way to deposit coatings on a substrate and can be used for a range of nanotechnological products, such as powders, ultra-thin coatings, aero gels and fibers.

Properties that can be achieved with sol-gel nanocoatings include:

  • Hydrophobic surfaces
  • Anti-fingerprinting
  • Oleophobic surfaces
  • Anti-microbial surfaces
  • Easy to clean surfaces
  • Protective transparent coatings
  • Corrosion resistance
  • Low friction
  • Chemical resistance
  • Antistatic surfaces
  • Conducting/semi-conducting surfaces
  • Extreme mechanical wear resistant properties
  • UV protection

Typical end-user markets include construction (pipes, facades, bridges), automotive (paint surface treatments, metal parts, metal structures, window, mirrors and lamps, plastic hoods), marine, electronics (components, screens and displays, plastic and metal parts), sanitary, oil and gas (pipes), energy (wind power structures and blades, glass surfaces on solar panels), consumer electronics (displays and plastic and metal parts) and food manufacturing.
