The surface state of soda-lime glasses before and after ultrasonication pretreatments with water, acetone, ethanol, water/ethanol/NaOH solutions, and UV/O₃ treatment were estimated using atomic force microscopy（AFM）and Fourier-transformed infrared spectroscopy with attenuated total reflection mode（FT-IR-ATR）. Ultrasonication with water/ethanol/NaOH solutions and UV/O₃ treatments drastically decreased the size and number of surface contaminant particles and enhanced absorption of the isolated silanol and hydrogen-terminated silanol. The Cu（OH）₂/Cu（O,S）bilayers were prepared using chemical bath deposition（CBD）in aqueous solutions containing copper（II）nitrate hydrate, ammonium nitrate, and urea or thiourea on glass substrates treated with water/ethanol/NaOH solutions. Top metallic Cu layers were then formed chemically by simple immersion of the bilayers into a NaBH₄ aqueous solution. The sheet resistance decreased with increasing immersion time, leading to 0.68 Ω/□ sheet resistance and 3.3×10⁻⁵ Ω cm resistivity after 10 min immersion. The adhesion strength was estimated using the tape peeling off test with a tensile testing machine and adhesion tape. The Cu/Cu（OH）₂/Cu（O,S）bilayer fabricated by chemical reduction for 10 min exhibited maximum and average adhesion strengths of 13.3 N/cm and 11.0 N/cm, respectively. The adhesivity was inferred to have originated from hydrogen bonding between the oxygen ions in Cu（O,S）and -OH- in silanol of the glass substrate.

A new plating pretreatment method on polyphenylene sulfide（PPS）resin surface with glass beads was studied. This method produced a PPS surface with micropores created via expansion and destruction of the glass beads caused by the reaction of oxalic acid and calcium. When plated, the micropores provided an anchor effect, consequently improving adhesion between the plating and PPS.
