According to a study from Southampton, the United Kingdom, "In the presence of a suitable surfactant, such as hexaclecyltrimethylammonium chloride or bromide, highly reflective and hard lead dioxide coatings with a black appearance can be electrodeposited from methanesulforric acid media at room temperature (295 K). The reflective PbO2 coatings are compact, adherent to the (vitreous carbon or carbon-polymer) substrate and can be formed at current densities of 10 to 100 mA cm(-2) at a thickness up to several hundred microns."
"The coatings were characterised by measurement of surface optical reflectance, surface roughness, surface microstructure, phase ...
