A simple, highly efficient route to electroless gold plating on complex 3D printed polyacrylate plastics

Compared to tedious, multi-step treatments for electroless gold plating of traditional thermoplastics, this communication describes a simpler three-step procedure for 3D printed crosslinked polyacrylate substrates. This allows for the synthesis of ultralight gold foam microlattice materials with great potential for architecture-sensitive applications in future energy, catalysis, and sensing. We develop a simple, highly efficient route to electroless gold plating on complex 3D printed polyacrylate plastics.
