“…This will extract the necessary information from a smaller scale and transfer it to a higher scale to take the effect of micro-and nanoscale phenomena, such as agglomeration, dispersion, and aspect ratios, of nanofillers [157,158]. Eshelby-Mori-Tanaka (EMT) [159,160], a micromechanical computation model, has been used by researchers to predict the nanofillers' effect in final polymer composites. The method does not capture the atomistic interactions of nanofillers and matrix aspect ratios.…”

Fused deposition modelling (FDM) has attracted researchers’ interest in myriads of applications. The enhancement of its part using fillers to print nanocomposites is a cutting-edge domain of research. Industrial acceptance is still a challenge, and researchers are investigating different nanofillers and polymer matrix combinations to investigate FDM-printed nanocomposites. Carbon nanotubes, graphene, and cellulose are heavily studied nanofillers because of their astonishing properties, biocompatibility, and ability to tailor the final performance of the FDM-printed nanocomposite part. This work presents a comprehensive review of polymer nanocomposites based on these nanofillers. Important examples, case studies, and results are discussed and compared to elaborate the understanding of the processing of nanocomposites, filaments, printing, and the characterisation of these nanocomposites. A detailed and exhaustive discussion of the prospective computational models, with challenges and a future road map, is provided, enabling the scientific community to understand these nanocomposites and their FDM processing for wider industrial applications and acceptance.

“…Moreover, in some research, the mechanical properties of CNT-enhanced composites have experimentally been studied by observing the effects of interfacial bonding between polymer matrix and fillers, [27] particles agglomeration, [28,29] and fillers dispersion. [30][31][32][33] Although many successful performances of nanocomposite foam sensors have been reported, some deficiencies still exist. [34,35] The majority of the sensors that were studied in the literature suffer from low Young's modulus, inferior recoverability, low mechanical durability, and weak compressive strength.…”

In recent years, novel features of ultra‐flexible nanocomposite foams have drawn tremendous attention toward these materials to be utilized in a variety of engineering applications. Since Young's modulus of nanocomposite foams is related to their mechanical strength and directly affects their applications, in this study, this property was evaluated experimentally and theoretically. In this regard, polydimethylsiloxane (PDMS)/multiwalled carbon nanotube (MWCNT) nanocomposite foams with different filler contents (e.g., 0.1, 0.25, and 0.5 wt%) and different porosities (e.g., 60%, 70%, and 80%) were fabricated by solvent casting and particulate leaching methods. The results suggested that the optimum value for foam porosity and MWCNT content is required to elevate Young's modulus of nanocomposite foams. The experimental data indicated that in the samples with 60% porosity increasing MWCNT content improved Young's modulus of the samples; however, in the samples with 70% porosity Young's modulus was elevated when the filler content was up to 0.25 wt%. Moreover, using the experimental data, a theoretical approach was successfully extended to predict Young's modulus of nanocomposite foams with the combination of different void fractions and CNT contents.

“…The effects of various porosity forms, porosity coefficients, length scale, excitation frequencies and lumped on the natural frequency and voltage output of nanobeams were investigated. Moradi-Dastjerdi et al 40 proposed a PEH made of an advanced porous nanocomposite substrate activated by two piezoceramic layers. The advanced passive layer is made of a lightweight polymeric foam which reinforced with carbon nanotubes.…”

This study deals with piezoelectric energy harvesters carrying the magnet at the free end while a magnifier connected them to the base. The harvester consists of a cantilever beam with Functionally Graded (FG) porous foam core and two piezoelectric faces while taking into account the von-Karman strains and the magnetic interaction of two magnets. The governing equation has been developed using Hamilton’s principle and reduced-order via the Galerkin method. Frequency response of vibrations and voltage derived using harmonic balance method and the adjusted model has been confirmed by parametric studies of the lumped parameter model. A parametric study is also performed to expose the effects of porosity coefficient and pattern, magnifier ratios, and excitation level on the responses. Results show that by correct selection of the magnifier parameters, the proposed harvester can provide a higher output over a wider frequency band. Also, the core porosity increases the flexibility of the beam and raised the voltage by a factor of 1.8.
