| 為了增加納米銀粉的穩(wěn)定性，減少納米銀粉的團(tuán)聚性，提高納米銀粉與有機(jī)材料的親和性，需要預(yù)先對(duì)納米銀粉進(jìn)行表面改性。采用硅烷偶聯(lián)劑KH-560對(duì)納米銀粉進(jìn)行表面改性，以改性后銀粉作為填料制備導(dǎo)電膠，研究了納米銀粉用量與銀漿料導(dǎo)電性能之間關(guān)系，并借助TEM、紅外光譜、紫外可見(jiàn)分光光度計(jì)等測(cè)試手段，對(duì)改性后納米銀粉進(jìn)行表征。結(jié)果表明，經(jīng)表面改性后的納米銀粉，具有良好的親和性和分散穩(wěn)定性。改性機(jī)理為 KH-560 在少量乙醇的水溶液中水解為硅醇,生成 Si-OH 基團(tuán)，這些基團(tuán)上的羥基與 Ag 微粒表面的少量羥基發(fā)生脫水反應(yīng),生成了 Si-O-Ag 鍵。納米銀導(dǎo)漿料最佳的固化時(shí)間為 15 min。漿料的粘度隨納米銀含量增大而增大。納米銀粉含量在55%時(shí)的體積電阻率最小，值為2.5×10-3Ω•cm。 |

| In order to increase the stability of nano-silver,to Reduce the aggregation of nano-silver,to improve the affinity of Nano-silver and organic materials .It is required for surface modification of nano-silver.Using silane coupling agent KH-560 modified nano silver surface to prepare the modified silver conductive adhesive as a filler, the modified silver conductive adhesive as a filler.Amount of nano silver and silver paste the relationship between conductivity and the help of TEM, IR, UV-visible spectrophotometer, such as testing methods to characterize the modified Hou Nami silver. The results showed that after surface modification of nano silver, has a good affinity and dispersion stability. KH-560 modified mechanism is a small amount of ethanol in the hydrolysis of silicon-alcohol solution to produce Si-OH groups, these hydroxyl groups and the Ag particles on the surface of a small amount of hydroxyl dehydration reaction of the Si-O-Ag bond . The best guide nano-silver paste curing time for 15 min. The viscosity of slurry with nano-silver content increases. Nano-silver content of 55% of the volume resistivity in the smallest value of 2.5 × 10-3Ω • cm. |
