Faculty of Chemical and Natural Resources Engineering AbstractCation exchange membranes are regarded as the ideal solid polymer electrolyte materials for the development of various electrochemical energy conversion applications where significant improvement in the current density are required. Such membranes require special polymers and preparation techniques to maintain high chemical, mechanical and thermal stability in addition to high ionic conductivity and low resistance. A lot of different techniques have been proposed in the past to prepare such membranes. Radiation-induced graft copolymerization provides an attractive method for modification of chemical and physical properties of polymeric material and is of particular interest in achieving specially desired cation exchange membranes as well as excellent membrane properties. This is due to the ability to control the membrane compositions as well as properties by proper selection of grafting conditions. therefore numerous parameters have to be investigated to properly select the right polymeric materials, radiation grafting technique and the grafting conditions to be employed. In this paper a state-of-the-art of radiation-induced graft copolymerization for preparation of cation exchange membranes and their applications are briefly reviewed.
Membran penukaran kation dianggap sebagai bahan elektrolit polimer dalam pembangunan mengenai pelbagai kegunaan keabadian tenaga elektrokimia dimana pembaikan ketumpatan arus yang bererti diperlukan. Membran sedemikian memerlukan teknik dan polimer khusus bagi menjamin kestabilan kimia, mekanikal dan haba yang tinggi sebagai tambahan kepada kekonduksian ion yang tinggi dan rintangan yang rendah. Banyak teknik berbeza telah dicadangkan pada masa lalu bagi menyediakan membran tersebut. Kopolimerisasi graf teraruh sinaran merupakan satu kaedah yang menarik dalam pengubahsuaian sifat kimia dan fizikal bahan polimer dan sangat disukai terutama bagi mendapatkan membran penukaran kation khusus mengawal komposisi dan juga sifat sifat membran secara memilih keadaan penggrafan yang sesuai. Oleh kerana itu, berbagai parameter perlu diselidiki untuk memilih bahan polimer sesuai, teknik penggrafan sinaran dan keadaan yang hendak digunakan. Dalam kertas kerja ini perkembangan mengenai pengkopolimerisasi dalam menyediakan membran penukaran kation dan penggunaannya diulas. | Item Type: | Journal |
