Polymer coating method advantages

Pigmented polymer coatings on steel and PTFE as well as PTFE-based copolymers can be analyzed by rf-GD-MS in order to fingerprint them [648]. Advantages compared with SIMS and x-ray photoelectron spectroscopy are that the method is fast and does not require dissolution of the sample, and thermal volatilization processes do not appear to take place. 

The photocorrosion of the semiconductor has been reduced by the polymer coating. The simultaneous generation of Hg is zm advantage of this process. This method gives a power conversion efficiency of 0.6% and a quantum efficiency of nearly 1%. 

The thickness of the film obtained is directly proportional to the concentration of the nanocomposite solution or suspension. This method is advantageous since the thickness of the polymer-coated film on the electrode can be known from the original concentration of polymer solution and droplet volume. This technology is rather simple and there is no waste of material like spin-coating technology. However, the resulting film is usually not uniform and controlling of thickness for the film is very difficult. Moreover, the quality and thickness of polymer film formed by...
