“…However, literature regarding the usage of PBS or PBSA as a polymer matrix is somewhat scarce. Biodegradable polyesters such as PLLA [ 41 , 42 , 43 , 44 ] as well as regular synthetic polymers such as polyolefins [ 45 , 46 , 47 ], polyamides [ 48 ] and polyurethanes [ 49 ] are more widely researched as polymer matrices in carbon-filled composite applications. In a study by Alruwail et al, a PBS/PLA blend composite filled with MWCNT was developed for gas-separation-membrane applications [ 50 ].…”

Electrostatic dissipative (ESD), anti-static (AS), and electromagnetic interference (EMI) shielding materials are commonly based on commodity fossil-fuel-based plastics. This, in turn, contributes to ever-growing non-biodegradable plastic pollution. Graphene nanoplatelets (GN), multi-walled carbon nanotubes (MWCNT), nanostructured carbon black (NCB), and amorphous carbon black (CB) were utilized as nanofillers to prepare bio-based and biodegradable poly(butylene succinate-co-adipate) (PBSA) nanocomposites. Solvent-cast composites were prepared with 1.1 to 30.0 vol.% nanoparticle loading. The literature mainly focuses on relatively low loadings; therefore, for this research, filler loadings were increased up to 30 vol.% but the maximum loading for NCB and CB loadings only reached 17.4 vol.% due to a lack of dimensional stability at higher loadings. The composites were characterized using tensile testing, volumetric and surface conductivity measurements, thermal conductivity measurements, dielectric spectroscopy in the microwave region, and transmittance in the terahertz range. Tensile tests showed excellent carbon filler compatibility and enhanced tensile strength for loadings up to 5 vol.% (up to 20 vol.% for MWCNT). The highest thermal conductivity values were reached for the MWCNT filler, with the 30.0 vol.% filled composite reaching 0.756 W/mK (262% increase over PBSA). All fillers were able to produce composites that yielded volume conductivities above 10−10 S/m. Composites with MWCNT, GN, and NCB inclusions above the percolation threshold are suitable for EMI applications in the microwave and THz frequency range.

“…57 Moreover, in the case of treated GNP/PU composite, the increase in the hydrogen bonding interaction between GNP filler and PU chains improved the interfacial bonding, consequently, a better load transfer ability was achieved. 63,64 At a higher GNP content, the decrement of modulus value was due to the defects present in the composite resulting from the agglomeration of GNP.

Shape memory polyurethane-based palm kernel oil (SMPU based PKOp) has been shown to possess good shape memory properties. However, SMPU based on vegetable oil bear poor mechanical properties, thus enhancing mechanical properties using reinforcement, such as graphene nanoplatelets (GNP) is favorable in term of performance and cost. Nevertheless, the high viscosity of the polymer and high surface energy of GNP are obstacles in achieving a good composite. Therefore, in this research, a series of acid functionalization process was conducted to enhance the distribution of GNP in SMPU matrix, as well as the effects of functionalized GNP on the mechanical and shape memory properties of PKOp based SMPU were investigated. Functionalized GNP-based SMPU composite (PU-F) reached maximum tensile strength at 1wt% of functionalized GNP, which is 150% higher compared to that of neat SMPU while tensile strain at break increased 1590% than that of neat SMPU at 0.25wt% functionalized GNP. However, the shape fixity was almost similar to that of pristine SMPU and all the composite samples exhibited 100% shape recovery.

As a result of nanotechnological advancement, parameters inducing flaws in shape memory polymers (SMP), such as weak mechanical properties, low electrical, and thermal conductivities, and so on, were mitigated through the inclusion of a versatile range of nanomaterials such as montmorillonites, carbon nanotubes, graphene and derivatives, cellulose nanocrystals, carbon nanofibers, and so on, thereby forming shape memory polymeric nanoarchitectures (SMPNs). Hence, this work elucidates most recently emerging advancements on multifunctional SMPNs filled by differing nanoparticulates. Varying multifunctional SMPNs exhibit responsivity to varying forms of stimulation strategies, including thermal responsivity, electroactivated, alternating magnetic field responsivity, light sensitivity, and water induced SMPs. Therefore, this article presents very recently emerging advancements in the construction, characterization, properties, and multifunctional applications of stimuliresponsive SMPNs, with special emphasis on functional and stimuli-responsive SMPNs. Furthermore, important functions of SMPNs such as stimuli-memory effect and self-mending abilities, as well as prospective strategies for future progress of these materials are highlighted.
