Abstract
There has been growing interest in fibre modification for several industrial
applications. The modifications have mostly been done to improve the fibre properties.
However, the information regarding fibre modification via click chemistry is still limited.
In this work, oil palm empty fruit bunch was extracted via Alkaline Peroxide Pulping
(APP). Then the extracted pulp was beaten to 8000 revolutions using PFI mill. The
resulting fibres were chemically modified using two strategies of click chemistry were
evaluated for modifying empty fruit bunch fibre without the addition of copper catalyst,
which was dispersibility and crosslinking. In both of these modification strategies, there
were two methods to modified the fibre. Crosslinking were characterized by Fourier
Transform Infrared spectroscopy, Scanning Electron Microscopy, X-Ray Photoelectron
Spectroscopy and Elemental Analysis, while dispersibility were characterized by Fourier
Transform Infrared Spectroscopy, light microscopy, particle size and zeta potential
analyzer. Click chemistry was found to successfully crosslinked and dispersed the fibers,
based on the tests conducted. These modified fibres would be an interesting application
for the packaging and moulded pulp products.
