Investigation of the effects of ionic liquids in the electroless metal plating process over ABS plastic
Project no. 352 · Status: Kapanmış · 2018
Summary
Metal plating on the plastic industry is developing rapidly in recent years in Turkey. Many importance of the metal-plating on plastics are: to be corrosion resistant, increasing the salability of the product with glossy or satin-looking metallic surfaces etc. Electroless plating is a fundamental step in the metal plating on the plastic. This step makes the plastic conductive and makes it possible to homogeneous and hard plating with desired thickness. The difference between electrolytic and electroless plating process is the electroless plating process does not need electrical energy. In this method, without use of electricity is provided uniform coating thickness on substrates. Many environmentally hazardous and hazardous chemicals are used for etching of the plastic material which to be coated with traditional method. Beside the hazards which are exposure of burning chemicals and cyanide, chromium causes cancer risk at especially electrolytic coatings, there are ergonomic hazards and powders that have explosion potential. Instead of them, using the room temperature ionic liquids (RTIL) is objective of this study. Ionic liquids are defined as compounds that are sensitive to the environment due to their low pressure that can be negligible, their high heat resistance, and a higher ionic conductivity, to be electrochemically rich, to have wide open liquid range, to have a range of high polar solubility. The electroless bath is one of the most important parts of the process. In the industry there are many distinct chemical materials both catalysts and activation solutions. But the cost of the electroplating process is the increasing depends on the activation solutions and catalysts that are imported from the other countries and exactly non-producing in Turkey. Therefore the main goal of this study is to investigate the effects of ionic liquids for environmental friendly electroless plating baths in the metal plating industry over ABS plastic. In this way, both it will be provided a significant benefit to public health, and it will be brought innovation to the metal plating industry with the environmental friendly ionic liquid catalyst.
