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.

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,
