| Summary: | This study was conducted to produce green composite from kenaf with better thermal
properties. Kenaf fibre was successfully prepared by chemi-mechanical method. Kenaf fibre was
firstly treated with sodium hydroxide (NaOH) at 6% w/w followed by acidic treatment with
different concentrations (0.5M, 1.0M and 1.5M). The PLA/kenaf nanofibre composites were
referred as KC0.5, KC1.0 and KC1.5 according to acid concentration used. Differential scanning
calorimetry (DSC) was done to investigate thermal properties of the composites. The glass
transition, crystallization and melting temperature shows similar trend where 1.0M treated fibre
composites gives better thermal properties than 0.5M and 1.5M treated fibre composites.
Transmission electron microscopy (TEM) micrographs suggested the nanofibre dispersion in
mixed-pattern; exfoliation and small agglomeration. |
