“…Figure 9 shows a Cole-Cole plot of the storage modulus G′ versus the loss modulus G″ for the neat PP and its organoclay nanocomposites at 230 °C. It was proposed that the logG′-logG″ should be similar if the microstructure does not alter [26]. The logG′-logG″ curve can also be used to elucidate structure differences of polymer materials at a fixed conditions such as a fixed temperature.…”

3D printing has attracted a lot of attention over the past three decades. In particular the Fuse Filament Fabrication (FFF) technique, general materials require low shrinkage during cooling and viscous behavior during extrusion through a nozzle. Semi-crystalline thermoplastics and their composites are of the relevance of new materials for 3D printing. However, the crystalline structures, for instance, may have a favorable impact on their printability. In this study, polypropylene/organoclay nanocomposites were prepared by melt extrusion using a twin-screw extruder. The effects of organoclay on the thermal, rheological and morphological properties were studied to evaluate the possibility of using the polypropylene/organoclay nanocomposites as the FFF 3D printing feedstock. Dioctadecyl dimethyl ammonium chloride (D18) was successfully used to modify the clay surfaces, providing a good dispersity and wettability of organoclay in the PP matrix.

“…Among those techniques, incorporation of nanofillers to form nanocomposites represents one of the pretty efficient ways to reinforce mechanical properties and enhance crystallization rate of PBS. Thus, various nanofillers such as layered silicate 15,25,26 , carbon nanotubes [27][28][29][30] , inorganic nanoparticles [31][32][33][34] , cellulose derivatives [35][36][37] , have been incorporated into PBS for improving physical properties. Graphene and graphene oxide (GO) show many supreme properties such as high mechanical strength, Young's modulus, thermal conductivity, gas barrier property, and etc., which makes them ideal reinforcing fillers for various polymer matrices [38][39][40] .…”

Graphene oxide (GO) was incorporated into poly(butylene succinate) (PBS) via a solution coagulation method to fabricate PBS/GO nanocomposites. Scanning electron microscope and transmission electron microscope observations indicated that GO with very thin layer dispersed in PBS uniformly and showed a good interfacial adhesion with PBS matrix. Differential scanning calorimetry analysis suggested that the crystallization ability of PBS increased first and then decreased with increase in the content of PBS. Isothermal crystallization kinetics investigation manifested that the overall crystallization rate of PBS increased first and then decreased with increasing PBS content while the crystallization mechanism remained unchanged. Polarized optical microscopy analysis indicated that GO worked as an effective nucleating agent for PBS. X-ray diffraction characterization suggested that incorporation of GO did not change the crystal structure of PBS. Both tensile testing and dynamic mechanical analysis witnessed the reinforcement in mechanical performance of PBS by incorporation of GO.

“…Similar phenomenon was reported for nano-CaCO 3 filled PBS composite by Chen. 29 However, a strong shear thinning effect and nearly linear viscosity curve were observed for the composites (6 and 8 wt% HNTs) within whole investigated frequency range. And the η* of PP/HNTs composites (6 and 8 wt% HNTs) were lower than pure PP.…”

Halloysite nanotubes (HNTs) were used to prepare polypropylene (PP) nanocomposites through a novel vane mixer. The effects of melt blend time and halloysite content on properties of composites were investigated. SEM analysis was performed to show that HNTs were well dispersed in PP matrix with the increase of mixing time. DSC showed both the degree of crystallinity and crystallization temperature increased due to the introduction of HNTs into PP, which indicating a potential nucleation effect induced by the nanotubes. TGA illustrated that the presence of HNTs had two opposite effects on the thermal behavior. A surface catalytic action of the halloysite speeded up thermal degradation of PP. However, this effect was reduced with improved HNTs dispersion. Rheological investigations revealed that rheological properties were significantly increased by the addition of low fraction of halloysite to PP. The 2 wt% HNTs nanocomposites reached maximum tensile strength because HNTs dispersed evenly in PP.
