Pbt surface energy
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. It is a thermoplastic (semi-)crystalline polymer, and a type of polyester. PBT resists solvents, shrinks very little during forming, is mechanically strong, is heat-resistant up to 150 °C (or 200 °C with glass-fibre reinforcement), and can be treated with flame retard… WebThe selective metallization process consisted of three main steps: 1) surface patterning with picosecond laser pulses in atmospheric conditions (air and room temperature), 2) treatment in a PdCl 2 -based seeding solution, and 3) selective metallization of the substrate via electroless copper deposition ( Figure 1 ).
