(2)平均セル径: 電子走査型顕微鏡JXA-6100P(日本電子株式会社商品名)によって測定した。
(3)細孔径分布: JIS K3832に準拠するPerm-Polometer(Porous Material Inc.商品名)を用いて、最大細孔径、細孔径分布および最少細孔径を測定し、平均細孔径を算出した。
(4)通気性: フラジール型通気性試験機を用い、JIS L1004により、通気性を測定した。すなわち、適切なオリフィスをテーブルに設置し、試験片を固定して空気を流し、その際のマノメーターの水位を読み取って、流量換算表から流量を算出した。
(5)柔軟性: オートグラフAGS-5KNB(株式会社島津製作所商品名)を用いて、元の厚さに対して50%につぶした時のひずみ−応力曲線を求め、それより柔軟性を算出した。
