Abstract
Dalam kajian ini, membran saringan molekular karbon (SMK) telah Berjaya disintesis daripada polieterimid. Cakera karbon berliang (diameter 20 mm, ketebalan 2.5 mm) sebagai penyokong telah disediakan terlebih dahulu daripada percampuran serbuk hitam karbon dan resin fenolik. Penyokong tersebut dilapisi dengan larutan polieterimid dan seterusnya melalui proses pirolisis pada suhu dan masa yang berbeza bagi menghasilkan lapisan saringan molekular.
In this work, carbon molecular sieve (CMS) membranes were successfully synthesis from polyetherimide. Porous carbon disks (diameter 20mm, thickness 2.5mm) as support were prepared first by agglomeration of fine powdered carbon black with phenolic resin. The polyetherimide solution was coated onto the support and then pyrolyzed at various temperatures and times to form molecular sieve layer.
