“…DC plasma operated in oxygen or nitrogen is a widely used technique to modify the surface of polymers like polyimides and PET, 25 and it has been used in the past also in the case of injection molded PLA. 17 Two demonstrators like the one presented in Figure 8 and two square samples were treated at 50 W and 100 W for 5 minutes.…”

Electroless nickel and copper metallization of 3D printed polymers like polylactic acid and polyethylene terephthalate glycol modified is presented. The plating process is tested on suitable samples, which reproduce the characteristic morphologies used in 3D printing of objects. An alkaline etching is used for both polymers in order to modify the surface properties and to enhance the adhesion and uniformity of the metallic coating. In the case of polylactic acid, a plasma treatment is applied as well to further improve adhesion of the metallic coating. For the activation of the surface, a tin free process involving an immersion in a palladium solution and subsequent reduction to form metallic nuclei is employed. Electrolytes are formulated and selected to operate in temperature ranges comparable with the glass transition temperatures of the polymers. Adherent and uniform layers of NiP (3-4% P wt) and Cu can be easily obtained for esthetic and functional applications, also on flexible substrates. Since its introduction in the early 1980s, 1 3D printing has acquired a great relevance for research and industry. In the beginning this technique, based on the sequential deposition of layers to obtain three dimensional objects from a virtual model, found application in rapid prototyping and custom made machine parts. 2 In the last few years however a new industrial revolution began, as home 3D printers can nowadays be easily purchased on the market. This fact is starting to change the common concept of mass production, since 3D printing has the potential to start a new form of handicraft: the customer can obtain the tridimensional model of the desired object and subsequently print it. The production of some goods can thus be moved from factories to homes, with potential advantages.3 Other recent applications for 3D printing have been found in medicine, where the possibility to 3D print scaffolds, 4 cell cultures 5-7 or even organs 8 has been investigated. Many 3D printing techniques exist, like stereolitography (SLA), 9 selective laser sintering (SLS) 10 or fused deposition modelling (FDM).11 Only the latter is however finding the cited commercial success due to the low cost of the materials and the ease of operation. Objects that are complicate or even impossible to manufacture with conventional techniques, can be produced in reduced time ranges with this technique. It is on the other hand expensive to manufacture metallic objects. Some 3D printing techniques are suitable for direct metal processing, like SLS, 10 while for all the methods it is always possible to print the objects and subsequently cast them in a foundry. These two ways are however difficult to apply if the goal is to keep the process inexpensive and homemade.Another possibility to achieve a metal finishing for 3D printed object is to metallize only the surface of the polymer used in the process. This makes possible to achieve the desired properties of the metals without performing a real bulk metal 3D printing.12 Metallization processes like PVD can a...

“…Susceptibility to corrosion must be taken into consideration since hydrogen ions are produced in the mechanism of redox reaction resulting in a pH of 2-3 ideal conditions for the occurrence of material corrosion. An application of applying copper-coated plastic for a exible pH sensor used in acidic circumstance was published, 23 thus our research team would like to observe the use of copper-coated polypropylene composite BPs in the DMFC operation condition. There are several techniques 24 for coating copper on a substrate, for example, adhesion with glue, sputtering, vacuum coating, spray coating, electroplating and electroless plating.…”

Polymer metallization is important for several applications but triggering of electroless deposition is problematic. A simple and inexpensive method to prepare the polymers for initiating the electroless copper deposition is successfully applied to Liquid Crystal Polymer and Polyethylene Terephthalate. The samples are prepared by incorporation of a small amount (<0.5 wt%) of metal–organic compounds (palladium, nickel, or copper acetates) in the molten polymers. During blending, the polymers are held at sufficiently high temperatures to thermally decompose the acetates, yielding the metallic particles (Pd, Ni, or Cu) which are used as the activators. After surface preparation, copper is deposited on polymers in an electroless bath including formaldehyde as reducer. The influence of bath parameters (temperature, composition) and the nature of activators is investigated. This method can be extended to other polymers by finding an appropriate polymer/metal–organic couple. It is also demonstrated that cheaper Ni or Cu can substitute expensive Pd.
