摘要

無電解電鍍液配方是由許多添加劑所組成。本研究是探討配方內的安定劑成份及使用上對於布料鍍層表面的性能及鍍液穩定性的影響。
　　實驗方法是將安定劑原液以乙酸乙酯萃取後，以管柱層析方法進行純化分離之後再使用紅外線光譜儀(IR)、紫外光可見光光譜儀(UV/Vis)、核磁共振光譜儀(NMR)、差式掃描熱分析法(DSC)及基質輔助雷射脫附飛行時間質譜儀(MALDI-TOF/MS)等多種分析儀器對安定劑成份進行定性及定量分析。經分析結果已成功的鑑定出安定無電解電鍍液配方是由許多添加劑所組成。本研究是探討配方內的安定劑成份及使用上對於布料鍍層表面的性能及鍍液穩定性的影響。

　　第二部份是對無電解電鍍鎳液的安定劑置換成份的穩定性研究，經由置換成2-巰基噻唑啉安定劑的布料鍍層表面的性能與鍍液穩定性試驗結果發現，安定劑有添加或無添加的狀況下與原配方進行布料鍍層性能結果都相近，且在無添加安定劑下的連續式電鍍試驗結果的鍍液穩定性都呈現出良好的狀態。
　　目前的研究結果顯示，安定劑的存在與否在此無電解電鍍鎳液配方中並不影響電鍍結果。

Electroless nickel plating solution formulation is composed of different additives. This study is to investigate the ingredients of stability reagents and the influence on the performance of nickel coating layer on substrate surface and the stability of plating solution. In the experimental procedure：the stability reagent was extracted by ethyl acetate following column chromatography to separate the extracted components, qualitative and quantitative analysis were carried out by the following instruments：infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV/Vis), nuclear magnetic resonance spectroscopy (NMR), differential scanning calorimetry (DSC) and matrix-assisted laser desorption time of flight mass spectrometry (MALDI-TOF MS). The analysis results have successfully identified the main ingredient of the stability reagent as 2-mercaptothiazoline, and concentration of about 1800 ppm accounted for 60% of the total solids.
　　The second part is to test the function of an electroless nickel plating solution with replaced reagents 2-mercaptothiazoline. The tests include coating performance on fabric surface and the stability of plating solution. The similar result, were obtained between the original plating solution and with or without 2-mercaptothiazoline adding plating solution for all tests.
　　The current study showed that the presence or absence of stability reagents in this electroless nickel plating solution does not affect plating results.
