Description
第1工程ST11では、ルイス酸触媒の存在下、フリーデルクラフツ反応により、芳香族ポリエーテル系樹脂に置換反応用化合物を置換基として導入する。これにより、第1の実施の形態では、樹脂材料層の芳香族ポリエーテル系樹脂に任意の物性を発現可能な置換基を有する置換反応用化合物を導入できるので、従来の物理的及び化学的な表面処理では不十分であった樹脂材料層の各種物性の向上が可能となる。フリーデルクラフツ反応としては、フリーデルクラフツアシル化を用いてもよく、フリーデルクラフツアルキル化を用いてもよい。
置換反応用化合物としては、親水性官能基を分子内に導入できるものであれば特に制限はない。置換反応用化合物としては、分子構造中に炭素数5以上20以下のアルキル鎖、パーフルオロアルキル基、ポリエチレングリコール基及びシリル化された水酸基、末端二重結合及び末端三重結合などを有するハロゲン化アルキル、酸ハロゲン化物及び酸無水物などが用いられる。ハロゲン化アルキルとしては、例えば、塩化アルキル、臭化アルキル、ヨウ化アルキルなどが挙げられる。酸ハロゲン化物としては、酸塩化物、酸臭化物及び酸ヨウ化物などが挙げられる。
第2工程では、酸化剤などを溶解させた反応溶媒に、置換反応用化合物由来の置換基を導入した芳香族ポリエーテル系樹脂を浸漬させることにより、置換反応用化合物由来の置換基に親水性官能基を導入する。これにより、第2の実施の形態では、樹脂材料層の芳香族ポリエーテル系樹脂の主鎖から所定炭素数離れた領域に親水性官能基を導入できるので、親水性官能基の芳香族ポリエーテル系樹脂の分子構造内への潜り込みを防ぐことができる。また、親水性官能基が樹脂材料層の表面の接着剤及び塗料などと相互作用するので、親水性及び塗装性が向上するだけでなく、従来の物理的及び化学的な表面処理では不十分であった樹脂材料層の接着性の向上が可能となる。
ポリイミドフィルムを介して粉体状の芳香族ポリエーテルエーテルケトン0.2gをアルミ板で挟んだ状態で、プレス装置(型番「10TON TEST PRESS」、ゴンノ油圧機製作所社製)により370℃、60MPaの条件で加圧した後、室温まで徐冷して厚さ200μmの樹脂材料層を作製した。次に、作製した樹脂材料層を、4−ブロモベンゾイルクロリド0.32g、三塩化アルミニウム(AlCl3)1g及び反応溶媒を混合した反応溶液に、窒素雰囲気下で所定反応温度にて7時間浸漬処理してフリーデルクラフツ反応を実施した。反応溶媒及び反応温度を変化させてX線光電子分光分析により結合エネルギーと強度との関係を調べた。反応溶媒及び反応温度の条件を以下に示す。
(1)クロロホルム66.6g、23℃
(2)クロロホルム66.6g、43℃
(3)クロロホルム66.6g、70℃
(4)1,2,4−トリクロロベンゼン65.7g、100℃
(5)1,2,4−トリクロロベンゼン65.7g、135℃
(6)1,2,4−トリクロロベンゼン65.7g、150℃
ポリイミドフィルムを介して粉体状の芳香族ポリエーテルエーテルケトン3.0gをアルミ板で挟んだ状態で、プレス装置(型番「10TON TEST PRESS」、ゴンノ油圧機製作所社製)により370℃、60MPaの条件で加圧した後、室温まで徐冷して厚さ200μmの樹脂材料層を作製した。次に、作製した樹脂材料層を、10−ウンデセノイルクロリド0.68g、三塩化アルミニウム(AlCl3)2g及びクロロホルム133gを混合した反応溶液に窒素雰囲気下で60℃にて7時間浸漬処理してフリーデルクラフツ反応を実施した。次に、浸漬処理後の樹脂材料層をペルオキシ一硫酸カリウム(オキソン)24g及び炭酸水素ナトリウム12gを混合した反応溶液に浸漬し、常温で12時間浸漬処理することにより、10−ウンデセノイル基のビニル基をエポキシ化して表面処理後の樹脂材料層を得た。
・試験片形状:長さ60mm、幅10mm(なお、長さ方向30mmはアルミホイルを介在させて未接着部とした
・接着条件:ビスフェノールAジグリシジルエーテル100質量部と、硬化剤として4−メチル−1,2,3,6−テトラハイドロ無水フタル酸を87.5質量部とを添加した後、さらに促進剤として1−メチルイミダゾールを1.5質量部を加えた混合物を、常温で4時間真空脱泡したうえで使用してプレス装置により80℃で6時間,180℃で12時間後硬化させた
・樹脂材料層202,203の厚さ:0.2mm
・接着厚さ:できるだけ薄くして均一な接着層とした
・クロスヘッドスピード:50ミリメートル/min
フリーデルクラフツ反応を100℃で実施したこと以外は、実施例2と同様にして表面処理後の樹脂材料層を作製して評価した。
表面処理を実施せずに、接着強度を測定して評価した。
