Triboelectric nanogenerator (TENG), a green energy harvester, can harvest mechanical energy from human motion to electric energy to be applied in wearable electronics and sensor network. Porous materials played an important role in enhancing electric performance of TENG. In this paper, Azobisisobutyronitrile (AIBN) is used as a self‐reactive agent to modify Polydimethylsiloxane (PDMS) to form a self‐assembled porous structure (PDMS‐N10 film) through the difference in temperature between PDMS pre‐curing and AIBN decomposition. The PDMS‐N10‐based TENG exhibits a 2.5‐fold and 2.7‐fold improvement in output voltage and current as compared with PDMS without modification respectively. In addition, 116 light‐emitting diodes could be lighted up and 22 µF capacitor is charged. The TENG is also used as a sensor or trigger device for sensing the movements of elbow, knee, wrist, or finger, which can be applied in wearable devices because of the flexibility and durability as well as low cost.

“…In order to improve the performance of PDMS constructed TENGs, kinds of methods were applied for the modification of PDMS. [ 19–25 ] Modulating bulk friction materials is one of popular methods as it is convenient and effective. This method included doping nanomaterials and inserting sublayers, which is proposed to reduce the thickness of PDMS and increase the dielectric constant of PDMS, or filling electron capture materials.…”

“…[ 35,36 ] The mixture of propylene carbonate (PC) and ethylene carbonate (EC), which widely used in lithium‐ion batteries as high dielectric constant solvent, was chosen as liquid filling materials because that they were bad solvents for PDMS as well as high dielectric constant ε r (65 for PC and 90 for EC). [ 25 ] The good chemical stability, low vapor pressure, and low toxicity also make them suitable for fabrication of composite. [ 37 ] Moreover, this organic liquid is representative because of the property of transparency and dielectric which are typical characteristics of major liquids.…”

Material functionalization of triboelectric nanogenerators (TENG) plays an important role in TENG's electric performance for sustainable energy harvesting. In this work, a method for improving polydimethylsiloxane (PDMS) composites triboelectric performance has been proposed, via filling high dielectric constant liquid (instead of solids) into PDMS matrix. The improvement is attributed to the high dielectric constant liquid in PDMS matrix that reduced the effective thickness of PDMS and increased the dielectric constant of PDMS composite synchronously. At 50% filling ratio (PDMS‐HD50), the triboelectric performance exhibits an enhancement of 4.5‐fold in output voltage and 3.9‐fold in output current as compared to pure PDMS. The results, besides higher transparency, are superior to the results from traditional solid dielectric constant doping materials like BaTiO3 nanoparticle in PDMS. This work has proved potentials of dielectric liquid filling materials in fabricating TENGs and could be a guidance for exploring new liquid filling materials.

A negative pressure assisted mixing method was applied to prepare homogeneous graphene‐based polydimethylsiloxane (PDMS) composite. The problem of graphene agglomeration in polymer matrix was well overcome by using the graphene microsphere aerogels. They possess unique porous structure and excellent adsorption capacity, enabling the PDMS solution can uniformly fill into the reduced graphene oxide aerogel microspheres (rGOAMs) or GO aerogel microspheres (GOAMs) under reduced pressure. Raw reduced graphene oxide (rGO) and graphene oxide (GO) were added into PDMS by a simple ultrasonic assisted mixing method as a comparison. rGOAMs‐PDMS and GOAMs‐PDMS composites displayed higher tensile strength, Young's modulus and storage modulus than rGO–PDMS and GO–PDMS composites. In addition, the thermal stability of graphene‐based PDMS composites was also significantly improved. Finally, rGOAMs‐PDMS and GOAMs‐PDMS composites performed much better antibacterial activity than that of rGO‐PDMS and GO‐PDMS composites, which demonstrated that this kind of graphene‐based PDMS composites could display a great potential application in biomedical field.
