“…CNT can also be used to enhance composites with PLA matrix. Urtekin et al 129 used the bridging effect of CNT to enhance the interaction between PLA and polycarbonate (PC) before. By combining multi‐walled CNT containing different functional groups Non‐functionalized (MWCNT), hydroxyl‐functionalized (MWCNT‐OH), carboxyl‐functionalized (MWCNT‐COOH), and polycarbonate‐grafted multi‐walled carbon nanotube (PC‐g‐MWCNT) were compounded with PC/PLA in a twin‐screw extruder, resulting in good grafting of PC onto MWCNT and improved T g of the composites.…”

Polylactic acid (PLA) is a thermoplastic polyester that has received widespread attention for its environmentally friendly origin and excellent performance, and its potential to address the current problems of severe white pollution and scarcity of petroleum resources. This article focuses on the synthesis, modification, degradation and application of PLA. The main focus is on the modification of PLA with different environmentally friendly materials (natural organic materials, biodegradable polymers, inorganic minerals) in blends for defects such as the brittleness of PLA. In addition, the applications of PLA composites in the fields of construction, medical, packaging and oil and water separation are also introduced, which hopefully will provide some help to the promotion of PLA.

“…Hitherto, various combinations of polymer/nanofiller binary nanocomposite systems have been successfully fabricated and characterized. Recently, polymer-blend-based multicomponent nanocomposites have attracted great attention due to their potential in advanced applications [23][24][25][26][27][28][29][30][31]. PC-blend-based and PVDF-blend-based nanocomposites have been studied to extend their individual versatility.…”

“…The nanocomposites exhibited much higher electrical conductivity than PVDF or PCL composites at the same CNT loading. Urtekin and Aytac [28] investigated the addition of functionalized CNTs on the properties of a PC/poly(lactic acid) (PLA) blend. The thermal stability, tensile properties, and electrical conductivity of the blend were improved to different degrees after adding differently functionalized CNTs.…”

Polycarbonate/Poly(vinylidene fluoride)-Blend-Based Nanocomposites—Effect of Adding Different Carbon Nanofillers/Organoclay

Carbon black (CB), carbon nanotubes (CNTs), and graphene nanoplatelets (GnPs) individually or doubly served as reinforcing fillers in polycarbonate (PC)/poly(vinylidene fluoride) (PVDF)-blend (designated CF)-based nanocomposites. Additionally, organo-montmorillonite (15A) was incorporated simultaneously with the individual carbon fillers to form hybrid filler nanocomposites. Microscopic images confirmed the selective localization of carbon fillers, mainly in the continuous PC phase, while 15A located in the PVDF domains. Differential scanning calorimetry results showed that blending PVDF with PC or forming single/double carbon filler composites resulted in lower PVDF crystallization temperature during cooling. However, PVDF crystallization was promoted by the inclusion of 15A, and the growth of β-form crystals was induced. The rigidity of the CF blend increased after the formation of nanocomposites. Among the three individually added carbon fillers, GnPs improved the CF moduli the most; the simultaneous loading of CNT/GnP resulted in the highest moduli by up to 33%/46% increases in tensile/flexural moduli, respectively, compared with those of the CF blend. Rheological viscosity results showed that adding CNTs increased the complex viscosity of the blend to a greater extent than did adding CB or GnPs, and the viscosity further increased after adding 15A. The electrical resistivity of the blend decreased with the inclusion of carbon fillers, particularly with CNT loading.

The progress of Industry 4.0 and the advancement of robotic design are revealing a significant gap in the capabilities of current manufacturing techniques and the selection of materials that are available in electronics. Present‐day electrical systems largely rely on metals, but there is a driving need to develop new electrically conductive objects with a wide range of material properties, including expanded flexibility and softness, and with increasingly complex geometries. Electrically conductive composites can replace traditional metal‐based systems. In particular, thermoplastic composites become electrically conductive with the incorporation of conductive fillers or polymers while retaining to a large extent the processability of the thermoplastic matrix. This is where fused filament fabrication (FFF), an additive manufacturing (AM) technique capable of processing a variety of thermoplastic‐matrix feedstock materials, can be leveraged to create electrically conductive objects with new functionalities. While there is an increasing number of publications describing the FFF of electrical objects such as sensors and circuits, there is no comprehensive review outlining the functioning mechanisms, drawbacks, and advantages of FFF as applied to conductive materials. The present review fills this lacuna by offering a critical analysis of the specific challenges and solutions to promote FFF of electrically conductive polymers and composites.
