Article Synopsis
  • Metal-coated plastic parts are becoming popular in the automotive industry due to their lighter weight and sustainability compared to traditional metals, and sputtering is a more eco-friendly method of coating.
  • The study focuses on achieving thicker chromium coatings (up to 1600 nm) on polycarbonate substrates while avoiding defects like cracking and pinholes.
  • Results showed that while increasing thickness improved reflectivity, it also introduced more roughness and thermal stress; the best outcome without buckling was a maximum thickness of 1400 nm, with good adhesion confirmed in tests.

Article Synopsis
  • * The study details a method to create antimicrobial surfaces by embedding silver nanoparticles (Ag NPs) into a polycarbonate substrate through a two-step thermal annealing process.
  • * Results showed that the Ag NP-enhanced polymer effectively inhibited the growth of both Gram-positive and Gram-negative bacteria, demonstrating a cost-effective and scalable approach to improving surface hygiene.
