Description
F=η×v÷t (1)
[式(1)中、ηはせん断流粘度であり、分散液の粘度(Pa・s)を表す。vは分散液のずり速度(m/s)、tはせん断応力付与時の分散液の厚み(m)を表す。]
無機層状化合物としての天然鱗片状黒鉛(XD100、平均粒径250μm、伊藤黒鉛工業株式会社製)0.15gと、有機化合物としてのトルオイルパーオキサイド(ナイパーBMT、日油株式会社製)1.15gとを、分散媒としてのN−メチル−2−ピロリドン(NMP、室温粘度約2mPa・s)10gに分散させて分散液を調製した。分散液を高速撹拌装置(フィルミックス30型、プライミクス株式会社製)に投入し、処理温度40℃にて30分間撹拌した。このときのせん断応力は、5MPa(処理速度10m/s、分散液厚み2mm)であった。処理後の分散液を、ポリテトラフルオロエチレン製フィルターを用いて、300mLの水で洗浄し、その後更に100mLのアセトンで洗浄・ろ過した。残渣を70℃で3時間乾燥させることにより、有機化合物が付着した薄層化無機層状化合物を得た。
実施例1において、トルオイルパーオキサイドに代えて、2,5−ジメチル−2,5−ジ(ベンゾイルパーオキシ)ヘキサン(パーヘキサ25Z、日油株式会社製)1.15gを用いたこと以外は、実施例1と同様にして薄層化無機層状化合物を得た。
実施例1において、トルオイルパーオキサイドに代えて、2,2’−アゾビス(イソブチルニトリル)(和光純薬株式会社製)0.8gを用いたこと以外は、実施例1と同様にして薄層化無機層状化合物を得た。
実施例1において、トルオイルパーオキサイドに代えて、2,2’−アゾビス[N−(2−カルボキシエチル)−2−メチルプロピオンアミジン](和光純薬株式会社製)1.7gを用いたこと以外は、実施例1と同様にして薄層化無機層状化合物を得た。
実施例4において、鱗片状黒鉛を、平均粒径25μmの天然鱗片状黒鉛(青島田庄石墨有限公司製)に変更した以外は、実施例4と同様にして薄層化無機層状化合物を得た。
実施例4において、鱗片状黒鉛に代えて、平均粒径2.4μmのグラフェン(GNH−XZ、グラフェンプラットフォーム株式会社製)に変更した以外は、実施例4と同様にして薄層化無機層状化合物を得た。
比較例1〜3においては、実施例1、実施例5、及び実施例6で用いた無機層状化合物を、そのまま用いた。
実施例1〜6及び比較例1〜3の薄層化無機層状化合物又は無機層状化合物について、X線回折装置(EMPYREAN、PANALYTICAL社製)を用いて、広角X線回折法測定から求めた結晶子サイズと面間隔から積層数を算出した。具体的には、層構造に対応する002面に対応する2θピーク(26°付近)から面間隔を、以下の式(2)に示すシェラーの式及び式(3)により結晶子サイズを求めた。結果を表1及び表2に示す。
結晶子サイズ(nm)=Kλ/βcosθ (2)
β2=βe2−βo2 (3)
[式(2)及び式(3)中、K=0.9、λ=0.15406、βe:回折ピークの半値幅、βo:半値幅の補正値(0.07°)を表す。]
実施例1〜6及び比較例1〜3の薄層化無機層状化合物又は無機層状化合物について、熱重量測定(TG−DTA)により有機化合物の付着量を評価した。有機化合物の付着量については、昇温速度10℃/min、窒素雰囲気下、温度範囲30〜800℃の条件で熱重量測定を行い、以下の式(4)により算出した。結果を表1及び表2に示す。
付着量(質量%)=(B−A)/B×100 (4)
[式(4)中、Aは薄層化無機層状化合物の600℃における熱分解後の残存率を、Bは薄層化前の無機層状化合物の600℃における熱分解後の残存率を示す。]
実施例1〜6及び比較例1〜3の薄層化無機層状化合物又は無機層状化合物5mgを、10mLのNMP又はトルエン中に添加し、42kHzで30分間、超音波を照射した。超音波照射後、上澄み液を採取し、乾燥後の質量を秤量することにより上澄み液中に含まれる薄層化無機層状化合物(無機層状化合物)の質量を秤量した。比較例1〜3の無機層状化合物と比較して、質量が増加した場合を「○」、質量変化が見られない場合、若しくは質量が減少した場合を「×」として評価した。結果を表1及び表2に示す。
