Abstract
【解決手段】 本発明に係る多孔質シートの製造方法は、超高分子量ポリエチレン粒子を溶媒に分散させた分散液を作製する工程と、前記分散液をフィルム上に塗布して塗布層を形成する工程と、前記塗布層を焼成する工程と、前記塗布層に含まれる前記溶媒を除去する工程とを有することを特徴とする。

Description
即ち、本発明に係る多孔質シートの製造方法によれば、超高分子量ポリエチレン粒子の形状の大部分を維持し、かつ、隣接する粒子相互がその接触部位において熱融着すると共に、非接触部位を孔とするミクロ構造とすることができるので、剥離性、表面平滑性及び通気性に優れた多孔質シートの製造が可能になる。
UHMWPE粉末(平均分子量200万、融点135℃、平均粒子径30μm、粒子形状:球状)を、グリセリン及び界面活性剤と混合し、分散液を調製した。分散液の固形分は、40体積%とした。続いてこの分散液を、PETフィルム(商品名;ルミラーS10、厚み100μm)上にアプリケータを用いて塗布した。塗布層の厚さ(溶媒を含む)は250μmとした。
実施例1で用いた分散溶媒としてのグリセリンをイオン交換水に替えたこと以外は、実施例1と同様にして、本比較例に係る多孔質シートを作製した。
以上のようにして作製した各多孔質シートについて、表面粗さ、厚み、通気性及び摩擦係数をそれぞれ測定し、SEM写真観察を行った。それらの結果を下記表1に示す。尚、測定方法及び測定条件は以下の通りである。
各多孔質シートの表面粗さは、触針式表面粗さ計((株)東京精密、サーフコム550A)を用いて測定した。測定条件は、先端径R250μm、速度0.3mm/sec、測定長4mmとした。
各多孔質シートの厚さは、1/1000マイクロメータを用いて測定した。
各多孔質シートの通気性は、フラジール試験機を用いて測定した。通気性は、各多孔質シート全体の厚み方向に対する値である。
往復動摩擦試験機(バーデンレーベン式摩擦試験機)(オリエンテック(株)社製、AST−15B)によって、相手材としてポリエチレンテレフタレートフィルム(50μm)を用い、試験荷重200g、移動速度150mm/minの条件下での動摩擦係数を測定し、平均値を求めた。
多孔質シートの断面の走査型電子顕微鏡(SEM)写真により行った。測定条件は、倍率400倍、傾斜面15°とした。
