The effect of different silane coupling agent concentration towards physical and mechanical properties of polypropylene / banana composite / Shahira Adnan
Untreated and treated PP/BF composite had been prepared in this research using melt mixing process. The effect of different silane concentration (0.0%, 0.5%. 1.0%, 1.5% and 2.0%) for the BF treatment had been studied towards the physical and mechanical properties of the PP/BF composite.

| description | Untreated and treated PP/BF composite had been prepared in this research using melt mixing process. The effect of different silane concentration (0.0%, 0.5%. 1.0%, 1.5% and 2.0%) for the BF treatment had been studied towards the physical and mechanical properties of the PP/BF composite. FTIR spectra show the removal of some hemicellulose and the reduction of OH group on BF surface after chemical modification. As for tensile testing, the tensile strength and tensile modulus shows the increasing in trend with the increasing of silane concentration used. This is due to the better interfacial adhesion properties between BF and PP matrix. However, there are gradually decreased in percent elongation break of PP/BF composite by increasing silane concentration, due to stiffening effect of BF on the composite sample was increase. Besides that, there are gradually increased in impact strength of the PP/BF composite with the increase in silane concentration used during treatment process as compared to the PP/BF filled with untreated BF. This is due to the better interaction between fiber and polymer matrix. Other than that, the increase silane concentration used during treatment process had lead to the decrease in percent of water absorption of the PP/BF composite. This is due to the reduced amount of OH molecules that can interact with water molecule. The highest silane concentration used (2%) to treat BF imparts highest physical and mechanical properties. This is due to the better interfacial adhesion between BF and PP matrix was achieved, and also the decreased of the OH group in the fiber due to the chemical treatment that had been done. |
