実施例で得られた銅系ナノ粒子の耐酸化性について調べた。一般に、銅は酸化されやすい金属であり、ナノ粒子になることによってさらに酸化されやすくなることが知られている。そこで、合成した銅ナノ粒子のうち100 nm以下で融着が起こっていない粒子について、合成直後と1ヵ月後の粉末X線回折(XRD)を比較することにより耐酸化性を調べた。その結果を図30及び図31に示す。これらの結果からも明らかなように、平均粒子径(4.5±0.93 nm)が一番小さいCuNP/(C8)3N 1,2-DDOの際、合成直後と1ヵ月後の粉末X線回折(XRD)の亜酸化銅に帰属する回折パターンにわずかな増加がみられ、酸化の進行が確認された。また、平均粒子径がCuNP/(C8)3N 1,2-DDOより大きくなる、CuNP/(iPr)2NEt 1,2-DDO(平均粒子径(5.1±0.90 nm))について同様に耐酸化性を検討したところ、図32に示すように酸化が進行していなかった。さらに粒子径の大きい、CuNP/(2-EtC6)3N 1,2-DDO(平均粒子径(7.2±1.9 nm))図33、CuNP/(2-EtC6)3N
1,2-DDO・短時間合成(平均粒子径(9.65±2.07 nm))図34、CuNP/1,2-DDO(平均粒子径(24.15±13.94 nm))図35についても同様に耐酸化性を検討した。その結果、合成直後と1ヵ月後の粉末X線回折(XRD)の回折パターンはほぼ同じであり、Cu及びCu2OのXRDパターンの強度比に1%以上の変化は確認されなかった。また、合成直後の粉末X線回折(XRD)を比較すると、平均粒子径が大きくなるにつれて亜酸化銅に帰属する回折パターンが小さくなっていることが確認された(図36、図37)。
Cuナノ粒子ペーストによる焼成膜の特性
実施例1で合成したCuナノ粒子 CuNP/(C8)3N 1,2-DDOに、ポリエステル系分散剤と溶剤にターピネオールを加え、分散性を促進させるためにトルエン数滴を滴下した。トルエンが揮発逸散し、残存しなくなるまで混ぜ、金属含有率60wt%のペーストに調合した。
このペーストを用いてスクリーン印刷法により電極パターンを印刷し、大気中にて350℃×30分間焼成した後、窒素に3体積%の水素を含む還元雰囲気下で350℃×30分間焼成した。得られた焼成膜の電気特性を表1に示す。この焼成膜の比抵抗値は20μΩcm以下というバルクに匹敵する比抵抗値を示した。また、図38には、ポリイミドフィルム上に形成した配線パターンを示す。このように、本発明によるCuナノ粒子を用いたペーストは、配線形成用として好適に用いることができる。
Cuナノ粒子ペーストによる接合実験
実施例1で合成したCuナノ粒子 CuNP/(C8)3N 1,2-DDOに、ポリエステル系分散剤と溶剤にターピネオールを加え、分散性を促進させるためにトルエン数滴を滴下した。トルエンが揮発逸散し、残存しなくなるまで混ぜ、金属含有率60wt%のペーストに調合した。
このペーストを用いて無酸素銅の接合実験を行った。直径2mmと直径5mmのリング状無酸素銅を被接合材として、ペーストを直径5mmの無酸素銅リング表面の中央部に塗布し、直径2mmの無酸素銅リングではさんだ。まず、150℃に加熱し、300秒保持し、ペーストを乾燥させた。次に20MPaの加圧をかけ、所定の温度(300〜400℃)まで加熱し、その温度で300秒保持した。その後、圧力を加えることなく、自然放冷した。接合した継ぎ手のせん断試験の結果を図39に示す。これから明らかなように、このように本発明による銅ナノ粒子ペーストは10MPa以上の強度を有し、接合用途にも好適な材料である。
