ABSTRACT
The
effect of various multi-walled carbon nanotubes (MWNTs)
on the tensile properties of thermoplastic natural rubber (TPNR)
nanocomposite was investigated. The nanocomposite was prepared using melt
blending method. MWNTs were added to improve the
mechanical properties of MWNTs/TPNR composites
in different compositions of 1, 3, 5, and 7 wt.%. The results showed that the
mechanical properties of nanocomposites were affected significantly by the
composition and the properties of MWNTs. SEM micrographs
confirmed the homogenous dispersion of MWNTs in the TPNR matrix
and promoted strong interfacial adhesion between MWNTs
and the matrix which was improved mechanical properties significantly.
Keywords:
Mechanical properties; multi-walled carbon nanotubes; thermoplastic natural
rubber
ABSTRAK
Kesan
beberapa jenis nanotiub karbon berbilang-lapisan (MWNTs)
ke atas sifat tegangan getah asli termoplastik (TPNR)
telah dikaji. Nanokomposit tersebut telah disediakan melalui kaedah pencampuran
leburan. MWNTs ditambahkan untuk meningkatkan sifat mekanik
komposit MWNTs/TPNR, pada komposisi pengisi
berbeza iaitu: 1, 3, 5 dan 7% berat. Hasil kajian mendapati sifat mekanik nanokomposit
sangat dipengaruhi oleh komposisi pengisi dan sifat pengisi MWNTs.
Sementara itu, mikrograf SEM mengesahkan penyerakan MWNTs
yang homogen dalam matrik TPNR. Dengan demikian pelekatan antara
muka yang bagus antara pengisi MWNTs dan matrik TPNR ini menjadi asas kepada peningkatan sifat mekanik yang ketara.
Kata kunci: Getah asli termoplastik; nanotiub karbon
