Effects of silane crosslinking on thermal and morphological properties of Spartium junceum flour/high density polyethylene composites

In this study, the use of silane-crosslinking high density polyethylene/Spartium Junceum flour composites has been investigated.The silane grafting and composite production were carried out simultaneously in a one-step process using a mixing chamber of a Plastograph.Extraction in p-xylene revealed an increase in gel content with crosslinking.Therefore, storage in a high humidity sauna generated a higher degree of crosslinking in the composites than storage at room temperature.The thermal stability of the composite is greatly improved by crosslinking reaction, but it isn't affected by the vinyltrimethoxysilane crosslinker concentration.Differential scanning calorimetry measurements of the composites showed a lower crystallinity in the crosslinked samples as compared to the uncrosslinked ones.
