“…Binary polymer nanocomposites are a more effective EMI shield material than single polymer nanocomposites as the electrical percolation threshold of the binary polymer matrix is much lower due to the electrical double percolation effect as the nanofillers are preferentially located on a particular polymeric phase of the blend. Among different biodegradable polymer matrixes PLA/PBAT, PLA/PCL, PLA/TPU, PCL/TPU, polydimethylsiloxane (PDMS) and other combinations are extensively used as polymer matrices to fabricate different polymer nanocomposite materials 19–24 . In the present work, we have produced ester based TPU/PBAT‐based blend which is a rarely or seldom used combination for the fabrication of polymer nanocomposite materials.…”

Flexible and electrically conductive polymer nanocomposite materials are gaining popularity as EMI shield materials. Herein, we report the successful fabrication of Thermoplastic polyurethane (TPU)/polybutylene adipate‐co‐terephthalate (PBAT)/dodecyl amine modified multi‐walled carbon nanotubes (MWCNT)‐based biodegradable polymer nanocomposite films employing solvent mixing and casting technique. The FESEM analysis of the cryofractured TPU/PBAT blend (containing 50 wt% of both the polymers) is found to be perfectly co‐continuous. Field emission scanning electron microscopy (FESEM), High‐resolution transmission electron microscopy (HRTEM) analysis followed by a selective dissolution test of polymer nanocomposites revealed that MAm nanofillers are mostly confined to the PBAT phase. The electrical percolation threshold is found to be between 3 and 5 wt% of dodecyl amine modified MWCNT loading as the electrical conductivity and EMI shielding efficiency are found to be shifting from 10−4 to 0.827 S/cm and −29.4 and −36 dB respectively as the nanofiller loading is increased from 3 to 5 wt% keeping the thickness of the polymer nanocomposite films constant at 0.8 mm.

The development of degradable plastic foams is in line with the current development concept of being pollution free and sustainable. Poly(lactic acid) (PLA) microporous foam with biodegradability, good heat resistance, biocompatibility, and mechanical properties can be successfully applied in cushioning packaging, heat insulation, noise reduction, filtration and adsorption, tissue engineering, and other fields. This paper summarizes and critically evaluates the latest research on preparing PLA microporous materials by supercritical carbon dioxide (scCO2) physical foaming since 2020. This paper first introduces the scCO2 foaming technologies for PLA and its composite foams, discusses the CO2-assisted foaming processes, and analyzes the effects of process parameters on PLA foaming. After that, the paper reviews the effects of modification methods such as chemical modification, filler filling, and mixing on the rheological and crystallization behaviors of PLA and provides an in-depth analysis of the mechanism of PLA foaming behavior to provide theoretical guidance for future research on PLA foaming. Lastly, the development and applications of PLA microporous materials based on scCO2 foaming technologies are prospected.

“…Consequently, the nature of the matrix and the filler, their proportions, adhesion, and the production process will mainly determine the final composite characteristics. Specifically, by changing the constituent elements (polymer type, particles, and/or additives) it is possible to modify their physicochemical properties and create new multifunctional materials [11,12]. Specifically, magnetic CMs have acquired an important role due to their diversity of applications in fields such as electronics, aeronautics, and biomedicine [2,13].…”

Additive manufacturing technology has attracted the attention of industrial and technological sectors due to the versatility of the design and the easy manufacture of structural and functional elements based on composite materials. The embedding of magnetic nanoparticles in the polymeric matrix enables the development of an easy manufacturing process of low-cost magnetically-active novel polymeric composites. In this work, we report a series of magnetic composites prepared by solution casting method combining 5 to 60 wt.% of 50 - 100 nm commercial Fe3O4 nanoparticles, with a semi-crystalline, biocompatible and biodegradable polymeric blend made of polylactic acid (PLA) and polycaprolactone (PCL). The composites were extruded, obtaining 1.5 mm diameter continuous and flexible filaments for fused deposition modelling 3D printing. The chemical, magnetic and calorimetric properties of the obtained filaments were investigated by differential scanning calorimetry, thermogravimetric analysis, magnetometry, and scanning electron microscopy. Furthermore, taking advantage of the magnetic character of the filaments, their capability to generate heat under the application of low-frequency AC magnetic fields (magnetic induction heating) was analysed. The obtained results expose the versatility of these easy manufacturing and low-cost filaments, where selecting a desired composition, the heating capacity can be properly adjusted for those applications where magnetic induction plays a key role (i.e., magnetic hyperthermia, drug release, heterogeneous catalysis, water electrolysis, gas capture or materials synthesis).
