Initial deposition rate and appearance of deposited nickel on glass are measured to realize the role of a complexing agent in the electroless plating bath.
We evaluated carboxylic acids, hydro carboxylic acids and amino acids as complexing agent.
Among these complexing agents, carboxylic acids and hydro carboxylic acids indicated an acceleration effect and amino acids showed a retardation effect on the plating rate.
Deposited nickel particles are agglomerated ranging from 10 to 30nm in the early deposition stages.
Glycine among the complexing agents showed the smallest particle sizes in the initial deposition stages and nickel was uniformly deposited and distributed on glass.
Therefore, this may lead the improvement of the adhesion strength of deposited nickel on glass.
