چکیده
|
Guineacorn husk particulate filled poly(lactic acid) bio-composites were prepared by compounding with a single screw extruder and then injection moulded. the guineacorn husk particulate (ghp) filler was treated with a combination of alkali and silane treatments (alksil) and the content was varied from 0 - 40% at 10% intervals. the effect of the surface treatment on the mechanical properties of the biocomposites was investigated. the results showed that the tensile and flexural strength properties of the bio-composites produced from treated filler were greatly improved by 10% and 43% respectively as compared to the bio-composites produced from untreated filler at 40% ghp content and these properties decreased with increase in filler content. on the other hand,tensile and flexural moduli properties increased with filler loading with those of the treated filler bio-composites being respectively 12% and 17% higher than the untreated filler bio-composites. scanning electron microscopy (sem) of tensile fractured samples showed some filler pull out and also good bonding between the filler and matrix upon surface treatment.
