| Summary: | Lignocellulosic fibers seem to be among the best alternative substitution fillers in biocomposite. Among its usages includes
as particleboard (PB) and wood polymer composite (WPC) as it is abundantly available and its woody properties offers
great usability. However, several problems arise due to the high hygroscopicity of woody materials and less interfacial
adhesion between hydrophilic filler with hydrophobic petroleum based polymer. A variety of alkali treatments has been
reported in the enhancement of promoting better fiber morphology and thus reduce the water uptake behavior and increase
the compatibility. This paper intended to review the alkalization treatment using Sodium Hydroxide (NaOH) on natural
fiber surfaces, differentiate treated and untreated fiber surfaces and summarize the effective concentration of NaOH
which may be applied on certain wood species. The findings are hoped to be used as a guide throughout future researches. |
