filled SDBF uncompatibilized composite was shown in literature (Kumar et al., 2010).
Figure 8 delineated that there is a little sign of LLDPE matrix and delignified bam-
boo fiber decohesion for the ----in situ grafting or p-grafting even after increasing the
percentage of grafted content. In ----in situ grafting, the GMA/MA molecules at the
interface on one hand react with the hydroxyl groups on the bamboo fiber dispersed
phase and on the other hand, they are grafted on the LLDPE chain. The reactive GMA/
MA molecules act as bridges between the matrix and reinforcement phase. Likewise
MA-g-LLDPE on one side entangled with other LLDPE chains in the matrix phase,
due to structural similarity while other side react with the bamboo fibers at the inter-
face. Therefore, adhesion will depend on the number of bond formed at the interface
and the effectiveness of these entanglements which ultimately depends on the DG
or chain length. The extent of adhesion was like in that order adhesion ----in situ
GMA<adhesion ----in situ MA~adhesion p-MA as per tensile properties evaluation.

and pre (p)-grafted compatibilized composites [5% MA, c].
