Abstract

Jeden ze sposobów modyfikacji powierzchni materiałów separacyjnych charakteryzuje się tym, że w szklanym naczyniu umieszcza się membranę płaską z wygenerowanymi grupami hydroksylowymi, roztwór modyfikujący i dichlorometan, następnie szczelnie zamyka i miesza, korzystnie w komorze laminarnej w atmosferze gazu obojętnego korzystnie argonu lub azotu, w temperaturze od 20 do 40°C w czasie od 1 do 6 h, przy czym roztwór jest mieszany podczas całego czasu prowadzenia reakcji, po czym membranę usuwa się z naczynia szklanego, przemywa rozpuszczalnikami poprzez jej umieszczenie w zlewkach po kolei, acetonem, dichlorometanem i wodą, i suszy korzystnie w temp. od 40 do 60°C w czasie od 8 do 15 h.
