Main rheological results for CNT-containing polymer blends.
| Blend Constituents | CNT Amount (wt.%) | Processing Method | Rheological Behavior | Ref. |
|---|---|---|---|---|
| Polypropylene/Polylactide | 0.5–2 | Melt-mixing | Solid-like behavior induced by nanofiller network | [108] |
| Polycarbonate/Polypropylene | 1–10 | Melt-mixing | Non-terminal rheological response at low frequencies | [109] |
| Polypropylene/Polyamide12 | 0.94–3.67 | Melt-mixing and injection molding | Pseudo-plastic behavior | [110] |
| Polystyrene/Polylactide | 2 | Dilution of a masterbatch by melt-mixing | Mixed viscoelastic/solid-like due to the incomplete formation of the nanotube network | [111] |
| Polylactide/Polyethylene Oxide | 1–2 | Solution casting | A viscosity model was proposed, predicting complex modulus as a function of zero viscosity, yield stress, relaxation time and network breaking time | [112] |
| Polylactide/Polyethylene Oxide | 0.29–2.91 | Melt-mixing | Formation of a (pseudo-)network structure | [113] |
| Polylactide/Polybutylene Adipate Terephthalate | 0.25–4 | Melt-mixing | Appearance of a distinct shear-thinning behavior | [114] |
| Polylactide/Crosslinked Polyurethane | 0.1–1 | Melt-mixing | Transition from liquid-like to solid-like response | [115] |
| Styrene Acrylonitrile/Polyphenylene Ether | 1 | Solution casting and melt-mixing | Migration of functionalized CNTs into the Polyphentlene phase, leading to a decrease in both dynamic modulus and complex viscosity. | [116] |
| Polyethylene Oxide/Poly(methyl methacrylate) | 0.5–4 | Melt-mixing | Absence of zero-shear viscosity for CNT contents exceeding 4 wt.% | [117] |
| Polybutylene Succinate/High Density Polyethylene | 0.29-2.91 | Melt-mixing | Formation of a pseudo-network structure leading to enhanced complex viscosity and storage modulus | [118] |
| Polyamide6/Acrylonitrile Butadiene Styrene | 0.05–0.25 | Melt-mixing | Increased viscosity and storage modulus due to a reinforcing effect of the interface by the presence of MWNT | [119] |
| Polylactide/Polyethylene Oxide | 1–2 | Solution-mixing | Different values of the low frequency modulus were obtained depending on the prevailing effect between relaxation of Polyethylene oxide droplets and formation of CNT network | [120] |
