Influence of Organo-Sepiolite on the Morphological, Mechanical, and Rheological Properties of PP/ABS Blends

Abstract

To improve the poor impact toughness of polypropylene (PP), organo-sepiolite (O-Sep) filled 80/20 (w/w) polypropylene/poly(acrylonitrile-butadiene-styrene) (PP/ABS) nanocomposites were fabricated. The contents of O-Sep were correlated with the morphological, mechanical, and rheological behavior of PP/ABS/O-Sep blends. Scanning electron microscopy (SEM) was applied to study the morphology and thermogravimetric analysis (TGA) was applied to study the thermal stability. Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were applied to study the crystallinity. The obtained results show that O-Sep enhanced the dispersion of ABS in the PP matrix and increased the crystallinity of blends. The rheological results show that O-Sep could increase the viscosity, storage modulus, and loss modulus of blends. Moreover, the mechanical behavior shows that O-Sep (at proper content) simultaneously increased the tensile modulus, flexural modulus, and impact strength of PP/ABS/O-Sep blends.

Preparation of poly(eugenol-co-methyl methacrylate)/polypropylene blend by creative route approach: structural and thermal characterization

“…The thermal analysis results obtained in Fig. 7a, b are consistent with the results of similar materials prepared with polypropylene [38]. The thermal characteristics of the blend polymers obtained in the project are mostly close to the thermal behavior of polypropylene.…”

Flame-Retardant Performance of Epoxy Resin Composites with SiO2 Nanoparticles and Phenethyl-Bridged DOPO Derivative

“…SiO 2 nanoparticles were modified by a conventional strategy with modifications according to our previous study. 41 The detailed experimental procedure was as follows: first, SiO 2 was washed three times with ultrapure water and dried at 60 °C for 12 h, followed by the addition of dried SiO 2 to HCl/H 2 O (v/v 1:7) and stirring at room temperature for 1 h. After the reaction was continued for 24 h, the mixture was washed three to five times with ultrapure water, followed by drying at 60 °C for 12 h to prepare acidified SiO 2 . Second, the silane coupler CG-570 was dissolved in ethanol/H 2 O (v/v 18:1), and the solution pH was adjusted to 4−6 with formic acid.…”

Synthesis of Aluminum Phosphate-Coated Halloysite Nanotubes: Effects on Morphological, Mechanical, and Rheological Properties of PEO/PBAT Blends

“…Finally, HNTs@AlPO 4 was obtained after centrifugation, washing, and drying. To improve the interfacial compatibility between inorganic particles and organic polymers, HNTs@AlPO 4 was modified by a silane coupling agent, CG-570, to obtain organically modified HNTs@AlPO 4 (o-HNTs@AlPO 4 ) using our previously modified method [ 31 ]. The detailed procedure is as follows: 0.5 g silane coupling agent CG-570 was added into 60 mL ethanol/H 2 O ( v / v 18:1) and the pH of the mixed solution was adjusted to 4–6 with formic acid.…”

“…Urquijo et al blended PLA/PBAT with different carbon nanotube (CNT) contents and demonstrated that CNTs selectively located in the PBAT phase induced the coalescence of PBAT spherical particles [ 19 ]. Our previous work demonstrated that sepiolite (Sep) improved the toughness of PP/ABS, enhanced both the mechanical and thermal properties of PP/PA6, and functions as a nucleating agent and compatibilizer between polymers [ 31 , 32 ].…”
