| Summary: | 碩士 === 國立雲林科技大學 === 環境與安全衛生工程系 === 104 === Nickel-plated carbon fiber has many advantage: good rigidity, strength, small thermal expansion coefficient and specific gravity, lightweight and has properties of metal, best EMI of shielding efficiency and able to recycled utilization, it is widely used in the aerospace, defense and electronic products. For the preparation of nickel-plated carbon fiber, make the metal coat on carbon fiber with electroless plating, traditionally, it should conduct sensitization, activation process, but carried out sensitization, activation need to use toxic tin chloride and expensive palladium chloride, this study adopt a silane coupling agent APTS (3- aminopropyl trimethoxy silane) with 1,3,5,10,15 and 20 g replace traditional sensitization and activation process, then conduct electroless nickel plating experiment
Therefore, in order to replace the traditional post-sensitization, activation, this study used silane coupling agent about 1, 3, 5, 10, 15 and 20 g of APTS ((3- aminopropyl) triethoxy silane) treatment of carbon fiber, and then electroless nickel plating experiments and the analysis by SEM, EDX, FTIR, XRD and TGA.
Via SEM, EDX and FTIR results show, APTS really plating carbon fiber surface; The carbon fiber deal with 1g and 3g APTS can be successfully prepared nickel-plated carbon fiber; In XRD analysis showed 2θ = 32.5 ° when an amorphous phase structure NiP2 existence; The TGA analysis can be seen in 1 g APTS-CF / Ni its pyrolysis temperature is higher than after 3 g APTS-CF / Ni, represents 1 g APTS-CF / Ni has better thermal stability.
