“…FD values obtained in this study for samples PP‐ g ‐MHBP4, PP‐ g ‐MHBP5, and PP‐ g ‐MHBP6 (obtained with 9.0 wt % of MHBP) are higher than those reported by other authors, whose results were already mentioned earlier . The same occurs in the case of commercial samples of PP functionalized with MA, such as, Polybond 3200 (FD: 1.0 wt %), Polybond 3150 (FD: 0.50 wt %), G‐3003 (FD:1.2 wt %), E‐43 (FD:1.2 wt % ), Bondyran 1004 (FD:0.80 wt %).…”

The functionalization of polypropylene (PP) with a maleinized hyperbranched polyester polyol (MHBP) was performed in solution to obtain PP-g-MHBPs. The degree of functionalization (FD) increased with MHBP and dicumyl peroxide (DCP) contents, but the contact angle followed an opposite behavior. The sample obtained with the proportion of 9.0 wt % MHBP and 2.0 wt % DCP and presented the highest FD value. An FD value of 2.4 wt %, produced a reduction of 19 on the contact angle. It was observed by differential scanning calorimetry (DSC) that the PP-g-MHBPs obtained by employing 3.0 wt % of MHBP, exhibited a slight reduction of the melting temperature (T m ) with the increase in the amounts of FD and DCP. Some FD values obtained in this study are higher than those obtained both commercial and noncommercial grades of PP functionalized with maleic anhydride.

“…The increase in flexural strength and modulus may be due to proper dispersion of the filler in the matrix and improved adhesion qualities in the case of biocomposites with compatibilizer. From the results, it is obvious that use of Ma‐ g ‐PP as a compatibilizer increased chemical bonding at the matrix‐fiber interface by eliminating weak boundary layers as explained elsewhere …”

Potato peel powder (POPL), which is biodegradable, has been used as filler material in polypropylene (PP) matrix in varying concentration from 10 to 40% by weight to prepare biocomposites and investigated water absorption, physicomechanical and thermal properties. Scanning electron microscopy and X-ray diffraction has been used for morphological characterization and crystallization studies. Flexural modulus of biocomposites increased by 40% compared with neat PP at 30% loading of POPL. Flexural strength also increased with increasing filler loading. Tensile strength of biocomposites has been observed to be comparable with neat PP up to 20% filler loading and increase in tensile modulus up to 40% was seen in biocomposites with 20% filler loading. Impact strength of biocomposites up to 20% filler loading was found to be at par with neat PP. Use of MA-g-PP compatibilizer in the biocomposites yielded better physico-mechanical and thermal properties than biocomposites without compatibilizer. V C 2015 Wiley Periodicals, Inc. J. Appl. Polym.

“…Typically, a faster strain rate correlates to greater tensile strength in composites. This was supported by a study that found neat PP3825 had a strength of ~27 MPa and modulus of ~1.4 GPA when tested at a rate of 5 mm/min 32 . It appeared that BioC had poor bonding with the PP matrix, rendering it less efficient in stress transfer, as corroborated by other findings 2,11 .…”

polypropylene (pp) is an attractive polymer for use in automotive parts due to its ease of processing, hydrophobic nature, chemical resistance and low density. the global shift towards eliminating nonrenewable resource consumption has promoted research of sustainable biocarbon (BioC) filler in a pp matrix, but this material often leads to reduction in composite strength and requires additional fillers. Graphene nano-platelets (GnPs) have been the subject of considerable research as a nanofiller due to their strength, while maleic anhydride grafted polypropylene (MA-g-pp) is a commonly used compatibilizer for improvement of interfacial adhesion in composites. this study compared the thermomechanical properties of PP/BioC/MA-g-PP/GnP composites with varying wt.% of GnP. Morphological analysis revealed uniform dispersion of BioC, while significant agglomeration of GnPs limited their even dispersion throughout the PP matrix. In the optimal blend of 3 wt.% GnP and 17 wt.% BioC biocontent, tensile strength and modulus increased by ~19% and ~22% respectively, as compared to 20 wt.% BioC biocomposites. thermal stability and performance enhancement occurred through incorporation of the fillers. Thus, hybridization of fillers in the compatibilized matrix presents a promising route to the enhancement of material properties, while reducing petroleum-based products through use of sustainable BioC filler in composite structures.
