“…However, the tan δ values did not gradually decreased with more CNR used. Interestingly, an abnormal increase in tan δ values was observed for the PP/PBS/CNR (70/30/9) melt at low frequencies, attributed to the intensified CNR‐CNR interaction 14 . Furthermore, the PP/PBS/CNR (70/30/12) melt exhibited even lower tan δ values than the PP/PBS/CNR (70/30/9) melt, illustrating a stronger interaction among CNR.…”

“…The G ′ and G ″ plots at a frequency of 0.05 rad/s were illustrated as a function of CNR content in Figure S4. The inflection points could be regarded as the morphological percolation threshold 14 . Loss tangent tan δ curves were revealed more sensitively towards the morphological transformation (Figure 6c).…”

“…12 It is essential to selectively localize nanofillers in the governance of the blends' morphology. 13 The co-continuous morphology have been mediated with a large number of nanofillers, including silica, 14,15 nanoclay, 16,17 cellulose nanocrystal, 18 and synthetic nanorods, 5,19,20 etc. Specially, Janus particles, combining the amphiphilicity of a compatibilizer and the Pickering effect of a nanoparticle, 21,22 could impact the blends' morphology through a multiple viscoelasticity mechanism.…”

It is still a critical challenge to prepare engineering plastics with multi‐functionalities and high‐performances while considering their aesthetic properties and dyeing processes. In this study, a light‐colored conductive nanorod (CNR) was employed to mediate the morphology of immiscible polypropylene/poly(butylene succinate) (PP/PBS) blends. The CNR could be only located in polar PBS phase to effectively control the viscoelasticity ratio between binary phases. By incorporating just 9 per hundred resins (phr) of CNR, the sea‐island structure of PP/PBS (70/30) would transform a stable co‐continuous morphology of PP/PBS/CNR (70/30/9). The addition of CNR led to a significant reduction in blends' surface resistivity and volume resistivity. Simultaneously, the mechanical properties and appearance colors of the ternary blends were improved. The effect of CNR in morphological mediation was further verified with PP/poly(butylene adipate terephthalate)/CNR (PP/PBAT/CNR) and PP/poly(ε‐caprolactone)/CNR (PP/PCL/CNR) blends. In summary, this work provided a desirable engineering plastic, demonstrating permanent antistatic performance, improved mechanical properties and good colorability.

The blends of poly(butylene adipate‐co‐terephthalate) (PBAT), poly(propylene carbonate) (PPC), chain extender (ADR) and layered double hydroxides (LDH) are prepared by different extrusion methods. Effects of LDH and its distribution on rheology, phase morphology, mechanical properties, water vapor barrier properties and food preservation properties are investigated. Results show that when PBAT, PPC and LDH are mixed directly, LDH is preferentially distributed in the PBAT phase. When LDH are mixed with PPC firstly and then further with PBAT, LDH mostly migrates to the interface of PBAT and PPC. The epoxy groups of ADR react with the terminal groups of the polymers to improve the interfacial compatibility. Adding LDH, the mechanical properties and barrier properties of the materials are improved and by premixing of PPC and LDH, properties of composites are further improved. Compared with PBAT/PPC blends, the tensile strength and elongation at break of PBAT/PPC(LDH‐0.5)/ADR increased by 25.2% and 15.3%, respectively. The banana packaged in PBAT/PPC/LDH films maintains good freshness. It illustrates that PBAT/PPC(LDH)/ADR composites have a good application prospect in the field of barrier and food packaging based on their excellent mechanical, barrier and preservation properties.This article is protected by copyright.
