研究目的
Investigating the ability of various copper(II) complexes to act as effective precursors for laser-activated and electroless metallized polymer materials.
研究成果
Only the copper(II) coordinative polymer (complex A) was effective as a metallization precursor. The release of lattice H2O or CH3OH molecules in complexes B and C affected ablation and prevented successful metallization. TG-FTIR coupled analysis is a promising method to predetermine effective precursors.
研究不足
The study is limited to three specific copper(II) complexes and their effectiveness as metallization precursors. The applicability of TG-FTIR coupled analysis should be verified with a larger series of various metal–organic compounds.
1：Experimental Design and Method Selection:
The study evaluated three copper(II) complexes mixed with polyurethane resin to form coatings, which were then irradiated with an ArF excimer laser and electroless metallized. TG-FTIR coupled analysis was used to predetermine thermal properties of the compounds.
2：Sample Selection and Data Sources:
The complexes A, B, and C were synthesized as crystals and mixed with polyurethane resin to form coatings on polycarbonate plates.
3：List of Experimental Equipment and Materials:
ArF excimer laser (LPX 300, Coherent, USA), autocatalytic metallization bath (M-Copper 85, MacDermid, USA), thermogravimetric analyzer (Q500, TA Instruments, USA), spectrophotometer (Nicolet iS10, Thermo Scientific, USA), digital camera and microscope (DMS300, Leica, Germany), microscope (SU8010, Hitachi, Japan).
4：Experimental Procedures and Operational Workflow:
Coatings were irradiated with various numbers of laser pulses and fluences, then electroless metallized. Thermal degradation was examined by TG-FTIR coupled analysis.
5：Data Analysis Methods:
Degradation products were identified by Omnic Specta Software with incorporated Aldrich Vapor Phase Sample Library. EDX analysis was performed to assess copper content.
