技術分野
しかし、この化学組成からなるポリアミック酸溶液組成物を基材に塗布し、加熱処理して基材とポリイミド膜とからなる積層体を得ようとすると、発泡やフクレが生じ易く成形性に問題があった。このため、この化学組成からなるポリイミド膜は、通常、ポリアミック酸溶液組成物を基材に塗布し、得られた塗膜を加熱乾燥して自己支持性フィルムとし、次いで自己支持性フィルムを基材から剥がした後さらに加熱イミド化処理する方法によって得られている。
一方、この化学組成からなるポリアミック酸溶液組成物を基材に塗布し、加熱処理して基材とポリイミド膜とからなる積層体を得ようとすると、発泡やフクレが生じ易いという成形性の問題に加えて、得られるポリイミド膜は耐熱性などの特性が低くなり易いという問題があった。特に、取り扱いが容易で、好適に塗膜を形成し易い、比較的低分子量のポリアミック酸からなるポリアミック酸溶液組成物を用いた場合には、得られるポリイミド膜の耐熱性などの特性が、より低くなるという問題があった。
特許文献2には、前記化学組成からなるポリアミック酸溶液組成物の溶液を特定の有機極性溶媒を組み合わせた混合溶媒にすることによって、成形性を改良し、特性の優れたポリイミド膜を得ることができる、ポリイミド膜の製造方法が記載されている。
これらの文献では、溶媒についてはポリアミック酸を溶解する有機性極性溶媒を好適に用いているが、それらの溶媒と水と共沸する溶媒との混合溶媒については記載がない。
特許文献4では、前記問題を解決するために、耐熱ベース基板を、ポリイミド膜とそれを接着するための剥離樹脂層(ポリアミック酸)との2層で形成することが提案されている。しかし、2層化は工程が増えるので経済的でなく且つ制御も複雑になる。また剥離樹脂層をポリアミック酸で形成する必要があるために、ポリイミド膜を形成する際の同様の問題は十分には解決できていない。
(1) 基材表面に、下記化学式(1)で表される繰り返し単位を有するポリアミック酸が、有機極性溶媒と水と共沸する溶媒とを含み全溶媒中の水と共沸する溶媒の割合が5〜35質量%である混合溶媒中に溶解されたポリアミック酸溶液組成物からなる塗膜を形成して、基材とポリアミック酸溶液組成物とからなる積層体を得、次いで前記基材とポリアミック酸溶液組成物とからなる積層体を、少なくとも150℃超〜200℃未満の温度範囲で10分間以上加熱処理した後で、最高温度が400〜550℃の温度範囲で加熱処理して、基材とポリイミド膜とからなる積層体を得ることを特徴とするポリイミド膜積層体の製造方法。
なお、3,3’,4,4’−ビフェニルテトラカルボン酸類或いはピロメリット酸類とは、それらのテトラカルボン酸、それらの酸無水物、それらのアルコールのエステル化物などのポリアミック酸のテトラカルボン酸成分を構成することができるものである。
通常は、ポリイミド膜を製造する際には、十分な特性を達成するために対数粘度が2.0dL/gを越える比較的高分子量のポリアミック酸が用いられる。一方、対数粘度が2.0dL/g以下の比較的低分子量のポリアミック酸を用いた場合には、当該化学組成で得られるはずの特性を満たすポリイミド膜を形成することが難しくなる。特に、500℃以上の温度領域においても高い耐熱性を示す(熱分解を抑制してアウトガスの発生が少ない)ポリイミド膜を形成することは難しい。
本発明の混合溶媒の組合せとしては、とりわけ、有機極性溶媒としてN,N−ジメチルホルムアミド、N,N−ジメチルアセトアミド、N−メチル−2−ピロリドンからなる群から選択される一種以上の有機極性溶媒を用い、水と共沸する溶媒としてトルエン、キシレン、ピリジンからなる群から選択される一種以上の溶媒を用いることが好適である。
通常のフィルムを製造する際に用いられるそれ自体公知のベルト、ロール或いは金型などのフィルム形成用基材であってもよく、その表面にポリイミド膜を保護膜などとして形成する回路基板や電子部品、摺動部品などの表面に皮膜が形成される部品や製品、ポリイミド膜を形成して多層化フィルムを形成する際の一方のフィルムなどであってもよい。さらに、本発明においては基材とは、好ましくは特許文献3のようガラス板にポリアミック酸溶液組成物を塗布し加熱イミド化処理してポリイミド膜積層体を形成し、次いで、その上に、例えば透明電極層、アモルファスシリコン層、背面電極層などの他の材料をさらに積層する際に用いられるガラス板であってもよい。
例えば、ポリイミド無端管状ベルトが複写機の定着ベルトとして用いられるときは、熱伝導性を向上させるためにシリカ、窒化ホウ素、アルミナなどが好適に配合される。また表面に付着するトナーの融着防止のためにベルト表面にポリテトラフルオロエチレン、テトラフルオロエチレン−パーフルオロアルキルビニルエーテル共重合体、テトラフルオロエチレン−ヘキサフルオロプロピレン共重合体等のフッ素樹脂からなる非粘着性の層を積層しても構わない。
また、ポリイミド無端管状ベルトが複写機の転写ベルトとして用いられるときには、半導電性を付与するためにカーボンブラックなどが好適に配合される。

(溶液組成物の対数粘度)
対数粘度(ηinh)は、ポリアミック酸溶液をポリアミック酸濃度が0.5g/100ミリリットル溶媒となるようにN−メチル−2−ピロリドンに均一に溶解した溶液を調製し、その溶液を、30℃にて、キャノンフェンスケNo.100を用いて流下時間(T1)を測定した。対数粘度は、ブランクの溶媒の流下時間(T0)を用いて、次式から算出した。単位はdL/gである。
対数粘度={ln(T1/T0)}/0.5
ポリアミック酸溶液の固形分濃度は、ポリアミック酸溶液を350℃で30分間乾燥し、乾燥前の重量W1と乾燥後の重量W2とから次式によって求めた値である。
固形分濃度(重量%)={(W1−W2)/W1}×100
トキメック社製E型粘度計を用いて30℃での溶液粘度を測定した。
ポリアミック酸溶液の溶液安定性は、モノマー濃度20%に調製したポリアミック酸溶液についてE型粘度計にて30℃で溶液粘度の変化を測定することによって評価した。すなわち、調製直後のポリアミック酸溶液の溶液粘度をP1、5℃の雰囲気下で90日間放置後測定した溶液粘度をP2として、次式によって求めた溶液粘度の変化率が、±10%以下のものを○(良)とし、±10%以上となったものを×(不良)とした。
変化率(%)={(P2−P1)/P1}×100
株式会社マック・サイエンス社製の熱分析装置のTG−DTA2000Sを用い室温(25℃)から600℃まで10℃/minにて昇温を行い各温度領域における重量減少率を算出した。この重量減少はアウトガスの発生に起因すると考えられるので、本発明においては、この重量減少率をアウトガスの発生率の目安として評価した。
ガラス板上に10cm×10cmのポリイミド膜を製膜し、得られたポリイミド膜の表面を目視で観察した。フクレが生じている領域を観察し、フクレが生じている領域がない場合はA(良)、フクレが生じている領域が全面積の30%以下の場合はB(中間)、フクレが生じている領域が全面積の30%を越える場合はC(不良)とした。
攪拌機、窒素ガス導入・排出管を備えた内容積500mlのガラス製の反応容器に、溶媒としてN−メチル−2−ピロリドンの400.0gを加え、これにPPDの26.8801g(0.2485モル)と、s−BPDAの73.1199g(0.2485モル)を加え、50℃で10時間撹拌して、固形分濃度18.7%、溶液粘度5Pa・s、対数粘度0.65のポリアミック酸溶液を得た。このポリアミック酸溶液組成物にキシレンを50.0g(全溶媒量中の11質量%)添加して、均一に溶解したポリアミック酸溶液組成物を得た。
このポリアミック酸溶液組成物を、基材のガラス板上にバーコーターによって塗布し、その塗膜を、120℃、150℃にて各10分間、180℃にて60分間、200℃、250℃にて各10分間、450℃にて30分間加熱処理し、ガラス板と厚さが10μmのポリイミド膜からなる積層体を得た。
積層体のポリイミド膜表面の外観を目視観察した後、TGA測定をおこない500〜550℃、550〜600℃の温度範囲における重量減少率をアウトガス発生率の評価の目安として測定した。
