Description
CVD法によって、トルエンを原料として微細炭素繊維を合成した。
内径70mmで分散板付透明円筒に1g粉体を充填し、圧力0.1Mpa、容量1.3リットルの空気を分散板下部から送り粉体を吹出し、自然沈降させる。5回吹出した時点で沈降後の粉体層の高さを測定する。このとき測定箇所は6箇所とることとし、6箇所の平均を求めた後、嵩密度を算出した。
堀場ジョバンイボン製LabRam800を用い、アルゴンレーザーの514nmの波長を用いて測定した。
熱可塑性樹脂として、ポリカーボネート樹脂ペレット(日本ジーイープラスチックス株式会社製、レキサンHF1110)を、スクリュー径35mm、L/D=28の2軸押出機のメインホッパー口より投入した。次いで、参考例1で得られた微細炭素繊維を、表1に示す組成比にて当該2軸押出機のサイドフィーダー口より投入し、表1に示す押出温度、滞留時間、せん断速度にて溶融混練し、樹脂組成物ペレットを得た。
表2に示す組成比にて混合する以外は、実施例1〜6と同様にして、ポリカーボネート樹脂ペレット(日本ジーイープラスチックス株式会社製、レキサンHF1110)と、参考例1で得られた微細炭素繊維とを、表2に示す条件を用いる以外は、実施例1〜6と同様にして樹脂組成物を調製し、さらに平板状成形品を作成して、表面抵抗値を測定した。得られた結果を表2に示す。
熱可塑性樹脂として、ポリカーボネート樹脂に代えて、それぞれ、ポリアミド樹脂(東レ株式会社、アミランCM3007)(実施例7)、を用いる以外は、実施例2と同様にして樹脂組成物を調製し、さらに平板状成形品を作成して、表面抵抗値を測定した。得られた結果を表3に示す。
