Abstract

The focus of this research is to prepare epoxidised natural rubber (ENR)/poly(vinylidene fluoride) (PVDF) (ENR/PVDF) membrane using solution casting method and to characterize the ENR/PVDF membrane using universal tensile machine (UTM) and scanning electron microscope (SEM). Composite membrane of ENR/PVDF was prepared by solution casting technique. The tensile strain increases when ratio of ENR increases in the composite. SEM micrograph shows the compatibility of ENR and PVDF in 40/60 wt% sample but agglomeration of ENR in 60/40 wt% ENR/PVDF sample was observed. The micrograph also shows the existence of pores in the composite membrane which is essential when applying the membrane for separation of gas and waste water treatment.

 

Keywords:  composite membrane, epoxidised natural rubber, poly(vinylidene fluoride)

 

Abstrak

Fokus kajian ini adalah untuk menyediakan membran getah asli terepoksida (ENR)/ poli (vinilidina fluorida) (PVDF) (ENR/PVDF) menggunakan kaedah penuangan larutan dan untuk mencirikan membran ENR/PVDF menggunakan mesin ujian tensil (UTM) dan mikroskop imbasan elektron (SEM). Membran komposit ENR/PVDF telah disediakan menggunakan teknik penuangan larutan. Rintangan tegangan bertambah apabila ratio ENR bertambah didalam komposit. Mikrograf SEM menunjukkan kesesuaian ENR dan PVDF pada sampel 40/60 wt%  tetapi terdapat penggumpalan ENR pada sampel ENR/PVDF 60/40 wt%. Mikrograf juga menunjukkan kehadiran liang pada membran komposit tersebut dimana ianya penting untuk diaplikasikan sebagai membran pemisahan gas dan rawatan air buangan. 

 

Kata kunci:  membran komposit, getah asli terepoksida, poli (vinilidina fluorida)
