ABSTRACT
Nanocomposite thin films of
chitosan/graphene oxide (CS/GO) and chitosan/ EDTA-GO (CS/EDTA-GO)
were prepared by environmental friendly method and the properties were
compared. The experimental results showed fine dispersion of GO and EDTA-GO in CS matrix and some interaction occur
between the filler and the CS matrix that leads to better
distribution of stress transfer. At 0.5 wt. %, both CS/GO and CS/EDTA-GO experienced maximum tensile stress by 51 and 71% compared with CS.
Moreover, the elongation at break for both nanocomposites increases and the
amount of filler increases.
Keywords: Chitosan; functionalized
graphene oxide; graphene oxide; nancomposite thin films
ABSTRAK
Filem nipis nanokomposit kitosan/grafin
oksida (CS/GO) dan kitosan/EDTA-GO (CS/EDTA-GO)
telah disediakan dalam kaedah yang mesra alam dan sifat dibincangkan.
Keputusan eksperimen menunjukkan GO dan EDTA-GO sangat
larut di dalam matriks kitosan dan ini membantu dalam pemindahan
tekanan. Pada pengisian 0.5 wt. %, kedua-dua CS/GO dan CS/EDTA-GO menunjukkan
kadar kekuatan yang paling tinggi iaitu 51 dan 71% berbanding CS.
Selain itu, pemanjangan filem bagi kedua-dua nanokomposit bertambah
seiring dengan pertambahan pengisian.
Kata kunci: Filem nipis nanokomposit; grafin oksida; grafin oksida
