Description
(b)
(1)16〜25重量%のビニルコポリマー樹脂と、
(2)75〜84重量%の有機溶剤と
を含む15〜50重量%の有機媒体と
を含む。
この厚膜組成物中の電気的機能性粉末はAg導体粉末であり、Ag金属粉末、Ag金属粉末の合金、またはそれらの混合物を含んでもよい。粒径、形状、および金属粉末上に使用された界面活性剤は特に重要であり、適用方法に適していなければならない。
本明細書に記載の粉末は典型的に、機械混合によって有機媒体(ビヒクル)と混合され、印刷のために適したコンシステンシーおよびレオロジーを有し、「ポリマー厚膜銀組成物」または「ペースト」と本明細書では呼ばれる、ペースト状組成物を形成する。多種多様な不活性液体を有機媒体として使用することができる。有機媒体は、固形分が十分な安定度を有して分散性である有機媒体でなければならない。媒体の流動学的特性は、組成物に良好な適用性を与えるようなものでなければならない。かかる特性には、十分な安定度を有する固形分の分散、組成物の良好な適用、適切な粘度、チキソトロピー、基材および固形分の適切な湿潤能力、十分な乾燥速度、および荒っぽい取扱いに耐えるために十分な乾燥膜強度などがある。
本明細書に記載のポリマー厚膜銀組成物またはペーストは典型的に、ガスおよび湿気に対して本質的に不透過性であるポリエステルなどの基材上に付着される。また、基材は、プラスチックシートとその上に付着された任意の金属または誘電体層との組み合せから構成された複合材料など、不透過性プラスチックなどの軟質材料のシートでありうる。1つの実施形態において、基材は、金属化銀を含有する層の堆積でありうる。
(1)観察された特異な低い抵抗率(4.6ミリオーム/sq/mil)、および
(2)RFIDおよび他の用途に非常に重要であるプリントの厚さ(280ステンレス鋼スクリーンを使用して9〜10ミクロン)である。(1)および(2)の結果として得られるのは非常に低い回路抵抗であり、非常に望ましい有利な特徴である。
PTF銀電極ペーストを調製するために、界面活性剤としてステアリン酸を含有する4ミクロンの平均粒度を有する銀フレーク(範囲は1〜18ミクロンであった)を、塩化ビニリデンとアクリロニトリル樹脂とのコポリマー(Dow Chemical(Midland,Michigan)製のSaran F−310樹脂としても知られている)からなる有機媒体と混合した。樹脂の分子量は約25,000であった。銀粒子の表面積対重量の比は0.8〜1.3m2/gの範囲である。
64.00% ステアリン酸界面活性剤を有するフレーク化銀
35.50 有機媒体(19.5%樹脂/80.5%溶剤)
0.50 C−11溶剤
銀フレーク上の界面活性剤をステアリン酸からオレイン酸に変えて、別のPTF銀組成物を調製した。調合物の全ての他の特性、銀粉末分布、および後続の加工は実施例1と同じであった。すなわち、実施例1と同じ有機媒体を使用した。この組成物の正規化抵抗率は42.8ミリオーム/sq/milであった。銀フレーク上の界面活性剤の化学的性質の変化は、組成物の抵抗率に有意の(良くない)影響を与えることは明らかである。
粒度分布をより小さい粒子に変えて、別のPTF銀組成物を調製した。ここで、平均粒度が約2ミクロンに低減され、7ミクロンより大きい粒子は実質的になかった。実験例2の界面活性剤、オレイン酸を銀フレーク上で使用した。全ての他の加工条件は実施例1と同じであった。この組成物の正規化抵抗率は20.2ミリオーム/sq/milであり、選択された銀の粒度および使用された界面活性剤の重要性を再び示した。
別のPTF銀組成物を実施例1に従って調製したが、使用された樹脂を実施例1に記載されたビニルコポリマーから分子量25000の熱可塑性のポリエステル樹脂に変えた。全ての他の条件および加工は同じであった。測定された正規化抵抗率は22.7ミリオーム/sq/milであり、銀粉末と共に実施例1において使用された樹脂の重要性を立証した。
