[実施例1]
本発明において用いるナノカーボンの官能基は超臨界流体に溶解する性質があれば任意であるが、本実施例においては、下記[化1]で示される構造式を有するもの(以下、(1)と表す。)及び下記[化2]で示される構造式を有するもの(以下、(2)と表す。)を用いた。また本発明において、修飾するナノカーボンの種類は任意であるが本実施例においてはカーボンナノチューブを用いた。
表1は、(1)に示す構造を有するナノカーボン誘導体(カーボンナノチューブの化合物)a〜eについて示したものである。(2)の置換基R1〜R5がすべて水素である化合物を化合物a、R3のみメチル基で他の置換基が水素の化合物を化合物b、R3のみ塩素で他の置換機が水素の化合物を化合物c、R3のみヒドロキシ基で他の置換基が水素の化合物を化合物d、R3のみアミノ基で他の置換機が水素の化合物を化合物eとする。
本実施例に用いた金型及び成形装置の要部断面構造図を図1、プロセス模式図を図2に示す。図1中、7a〜7gは成形機の任意の信号をトリガーとして駆動する自動駆動弁であり、8a,8bは減圧弁、9a〜9dは手動開閉弁、10a〜10eは逆止弁、15a,15bはフィルターである。
前記化学式(2)の修飾カーボンナノチューブを用いた以外は実施例2と同様な装置を用い、同様な方法にてナノカーボンをポリマー内に浸透した。本実施例において作製したプラスチック試験片を超臨界抽出装置(ISCO社製 SFXシステム1220)にて分析したところ、圧力30MPaの超臨界CO2にて溶質が抽出された。該溶質をTEMにて観察したところCNT構造物が確認された。1HNMR分析により(2)の生成を確認した。
図3に示す成形装置を用い、実施例2と同様な修飾ナノカーボンを樹脂成形品表面に選択的に配向させた。熱可塑性樹脂は実施例1と同様な材料を用いた。本実施例に用いた装置は、CO2ボンベ18から超臨界流体発生装置3、更にナノカーボンやエントレーナと超臨界流体の攪拌槽4および金型へ導入するための自動弁7bまでの経路は実施例2に用いた装置と同様な構成である。本実施例においては、成形機可塑化シリンダー16内への超臨界流体および修飾ナノカーボンの導入は行わなかった。本実施例に用いた金型においては、固定金型24の表面に幅0.3mm深さ0.4mm長さ30mmの凹部溝23を2本、機械加工によって切削してある。該凹部溝23の両端における底部にはそれぞれ導入配管22に通じる孔が2本ずつ形成されている。
