Carbon nanomaterial-based nanogenerators for harvesting energy from environment

Graphene Nanosheets Enhanced Triboelectric Output Performances of PTFE Films

“…It is therefore summarized that the integration of two-dimensional (2D) materials and TENGs endows the exciting 2D-TENGs with enhanced output triboelectric performances and further extends the promising applications of TENGs in energy scavenging devices and self-powered sensors systems. 22,23 Friction and wear behaviors and the underlying sophisticated mechanisms of both the positive and negative tribomaterials in TENGs were of less concern in previous research studies. 24,25 Based on the numerous studies on the superlubricity (i.e., friction coefficient on the order of 0.001) of graphene and related 2D materials in recent years, 26−28 It is thus assumed that the filling of graphene materials into PTFE polymer films can not only lubricate the tribomaterials but also provide high output triboelectric performances in the derived TENGs, which makes them good candidates for the nextgeneration disruptive technologies and applications.…”

“…Moreover, Jiang et al have found that the optimum output voltage of the porous PDMS/MXene composite film-based TENG is seven times greater than that of the TENG based on the flat pure PDMS film. It is therefore summarized that the integration of two-dimensional (2D) materials and TENGs endows the exciting 2D-TENGs with enhanced output triboelectric performances and further extends the promising applications of TENGs in energy scavenging devices and self-powered sensors systems. , …”

High energy harvesting performance in flexible piezocomposites by synergistic design of the piezoelectric phase and conductive phase

“…35 Furthermore, CNTs with high conductivity were introduced into the optimal composition of BCZT/PVDF PC. 36 Compared to the conventional PC only with randomly dispersed 0-D piezoelectric ceramic fillers, the PC made from both piezoelectric phase and conductive phase has higher piezoelectric energy harvesting performance. We have theoretically analyzed the role of the CNTs, which has been supported by the finite element simulation.…”

Advanced Technology Evolution Pathways of Nanogenerators: A Novel Framework Based on Multi-Source Data and Knowledge Graph

“…As a novel energy solution for micro and wearable wireless electronic devices, nanogenerators (NG) have been developed to harvest energy from the environment, including biomechanical energy, solar and wind energy, thermal energy, etc. [ 1 ]. Based on different physical effects, nanogenerators can be roughly divided into piezoelectric nanogenerators (PENGs), triboelectric nanogenerators (TENGs), and pyroelectric nanogenerators (PYENGs) [ 2 ].…”
