Abstract
【解決手段】融着部材を含む融着サブシステムであって、前記融着部材が、基材と前記基材上に配置されたトップコート層とを含み、前記トップコート層が、フルオロポリマー中に均一に分散され、前記トップコート層に連続自己離型性表面を形成するフッ素化ナノ粒子を含む融着サブシステムである。

Description
オルトケイ酸テトラエチル約20.8部を、エタノール約100mL中の約5.1部のトリデカフルオロ(オクチル)トリエトキシシランに添加した。前記溶液を水酸化アンモニウム/エタノール溶液(エタノール約100mL中に約24mLの28% NH3・H2O)と混合し、室温で約12時間、激しく攪拌した。得られた混合物を約110℃で約1時間、空気中で加熱した。沈殿したフッ素化シリカ粒子を洗浄、濾過した。粒径分析装置(商品名:Nanotrac 252;Microtrac Inc.、フロリダ、ノース・ラルゴ)で測定した粒径は、約10nm〜約100nmの範囲であった。
フルオロポリマー複合材「AFC」を次のように調製した。二軸スクリュ押出機を、約20回転/分(rpm)のローター速度で約20分間使用して、約5グラムのフッ素化ナノ粒子と約50グラムのViton GF(E.I.du Pont de Nemous,Inc.から入手可能)を約170℃で混合して、約10pphのフッ素化ナノ粒子を含有するポリマー複合材を形成した。同様の手順を用いて、20pphのフッ素化ナノ粒子を有するフルオロポリマー複合材「BFC」、および30pphのフッ素化ナノ粒子を有するフルオロポリマー複合材「CFC」を調製した。
メチルイソブチルケトン(MIBK)に溶解した17重量%のフルオロポリマー複合材AFC、BFCおよびCFCをそれぞれ含有する3種のコーティング組成物ACC、BCCおよびCCCは、5pph(VITON(登録商標)−GFの重量に対する百分率)のAO700架橋剤(アミノエチルアミノプロピルトリメトキシシラン架橋剤;Gelest社製)および24pphのメタノールを配合して調製した。前記コーティング組成物ACC、BCCおよびCCCを、バーコーターで3つのアルミニウム基材にコートし、約24時間、49℃〜218℃での段階的加熱処理によりコーティングを硬化させた。
ギャップコートしたViton/F−NP複合材コーティング試料A、BおよびCについて、調製時のまま、ならびにW−20研磨紙を使用して研磨した後(試料AP、BPおよびCP)の表面自由エネルギーを測定した。研磨は、使用に先立ち、iGen Fuserロールに用いられるスーパー仕上げ手順を真似た。比較のために、Viton/AO700対照試料D、および表面上に堆積させたフッ素化ナノ粒子の層を有するViton/AO700コーティング(E)も作製した。それぞれのサンプルの表面自由エネルギーを、水、ホルムミドおよびジヨードメタンの3つの液体の液滴の接触角により測定した。表面自由エネルギーを表2に示す。試料A、BおよびC(調製時のままのギャップ塗工したViton/F−NP複合材コーティング)の表面自由エネルギーは、対照試料Dのものと同等であった。しかし、研磨により、10pphの試料APおよび20pphの試料BPについては、表面自由エネルギーが目標値18mN/m2(Tefron(登録商標)についての値)近くに低下し、30pphの試料CPについては、表面自由エネルギーがTeflon(登録商標)の値より低かった。さらに、30pphを添合することにより、Viton/AO700表面上にフッ素化ナノ粒子のオーバーコートを有する試料Eで観察された、約12mN/m2という非常に低い表面自由エネルギー値に近づく。
