“…When the temperature of deformed SMMF increases to more than the melting point of PW, the PW crystals will be melted, leading to the release of flexibility of MF. So, the deformed SMMF recovered to its original shape (recovery step). ,,, Because the amount of flexibility of MF is constant, the rate of shape recovery is influenced by the content of PW that is crystallized within the micropores of MF. Therefore, the concentration of PW solution and the soaking time of MF in this solution both affect the rate of shape recovery.…”

The development of triboelectric nanogenerators (TENGs) that exhibit enhanced durability and performance is crucial for their practical usage. Incorporating 3D and shape memory nanocomposites into TENGs is a promising strategy to achieve this goal. In this study, the effect of various oxide nanoparticles (Al 2 O 3 , SiO 2 , and TiO 2 ) on the TENG's performance was evaluated, and Al 2 O 3 was found to have the most significant impact. Subsequently, a shape memory melamine foam−poly(vinyl alcohol)− Al 2 O 3 [SM(MF-PVA-Al 2 O 3 )] nanocomposite was synthesized to fabricate a durable and high-performing TENG. The SM(MF-PVA-Al 2 O 3 ) nanocomposite has the ability to recover deformations and shape changes through heating (at 70 °C for 15 min), which restores the TENG's performance to its initial value without any noticeable difference. This recovery can be repeated multiple times. The resulting TENG exhibited a high performance (1325.96 V and 7.71 μA) and power density (70.99 mW/cm 2 ) and was capable of powering 110 commercial LEDs. Therefore, the SM(MF-PVA-Al 2 O 3 ) nanocomposite is a suitable material for fabricating TENGs with practical applications that are both high-performance and durable.
