Compatibilization Effect

The aim of this research is to improve compatibility of PBS/HDPE blend using HDPE-g-MAH as a compatibilizer. The effect of HDPE-g-MAH content on mechanical and thermal properties, and degree of crystallinity of PBS/HDPE/HDPE-g-MAH blend was investigated. The blends were prepared at PBS/HDPE weight ratio of 30/70 and HDPE-g-MAH was used at a content of 2, 4, 6 and 8 part per hundred of PBS and HDPE. The results showed that yield strength and stress at break of PBS/HDPE/HDPE-g-MAH blends insignificantly increased with adding HDPE-g-MAH more than 2 phr. In addition, addition of HDPE-g-MAH to the binary blends led to an increase of elongation at break while Young’s modulus of blends exhibited an insignificant change. The addition of HDPE-g-MAH into PBS/HDPE blend did not affect both flexural modulus and flexural strength. In addition, unnotched impact strength of the blends greatly increased with increasing HDPE-g-MAH content and PBS/HDPE blend containing 8 phr of HDPE-g-MAH were not fractured within the instrument limit. For thermal properties, the presence of HDPE-g-MAH did not affect degradation temperature of PBS domain and HDPE matrix. HDPE-g-MAH of 8 phr markedly influenced the degree of crystallinity of the PBS and HDPE.

This study reveals the enhancement of mechanical and thermal properties of maleic anhydride-grafted polypropylene (PP- g-MA) with the addition of nanocrystalline cellulose (NCC). A nanocomposite was manufactured by blending various percentages of PP, MA, and NCC nanoparticles by means of a twin-screw extruder. The influence of varying the percentages of NCC on the mechanical and thermal behavior of the nanocomposite was studied by performing three-point bending, nanoindentation, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Fourier-transform infrared (FTIR) spectroscopy tests. The novelty of this study stems on the NCC nanoparticles and their ability to enhance the mechanical and thermal properties of PP. Three-point bending and nanoindentation tests revealed improvement in the mechanical properties in terms of strength, modulus, and hardness of the PP- g-MA nanocomposites as the addition of NCC increased. SEM showed homogeneity between the mixtures which proved the presence of interfacial adhesion between the PP- g-MA incorporated with NCC nanoparticles that was confirmed by the FTIR results. DSC and TGA measurements showed that the thermal stability of the nanocomposites was not compromised due to the addition of the coupling agent and reinforced nanoparticles.
