Embodiment 1

[0037] 1. Materials

[0038] Polyglyceryl sebacate (PGS) is formed by the polycondensation of glycerol (99.5%, Sigma-Aldrich) and sebacic acid (99%, Sigma-Aldrich). Salt pellets were purchased from Shanghai Chemical Reagent Factory, China. Carbon nanotubes (CNTs) were purchased from Bailingwei Technology Co., Ltd. (99.9%, inner diameter: 5-10 nm, outer diameter: 10-20 nm, length: 10-30 μm).

[0039] 2. Preparation of Composite Samples

[0040]①Sebacic acid recrystallization. First, take sebacic acid in a three-necked bottle, set up the device, heat in a water bath at 78-80°C, then add ether until the sebacic acid is dissolved, take out the solution after the sebacic acid is completely dissolved, cool to room temperature, and filter with suction. The above process was repeated three times, and the sebacic acid obtained by the last suction filtration was poured into an evaporating dish (pad aluminum foil), covered with aluminum foil (perforated), and vacuum-dried at 60°C to o...

Abstract

The invention relates to a poly(glycerolsebacate) 3D printing nano generator and a preparation method and application thereof. The poly(glycerolsebacate) 3D printing nano generator is obtained by carrying out mixing, 3D printing, thermo-crosslinking and pore-forming agent dissolution on poly(glycerolsebacate) PGS, carbon nanotubes CNTs and a pore-forming agent in sequence. The poly(glycerolsebacate) 3D printing nano generator has high elasticity and electrical conductivity; and through the use of a 3D printing technology, the preparation process of most of the current flexible integrated TENGsis simplified, and the TENGs can be processed into complex and variable three-dimensional structures, so that the shape design has diversity and flexibility, thereby promoting the further developmentof flexible integrated 3DP-TENGs on wearable electronic devices.

Description

technical field [0001] The invention belongs to the field of nanometer generators, in particular to a poly(glyceryl sebacate) 3D printed nanometer generator and its preparation method and application. Background technique [0002] Wang Zhonglin's team reported for the first time the triboelectric nanogenerator (TENG), which can generate electricity through triboelectrification and electrostatic induction, and has become a new paradigm for obtaining mechanical energy from human motion and detecting human physiological activities. Due to the advantages of low cost, flexible structural design, and diverse raw materials, TENG has achieved rapid progress in both academia and industry. Considering the potential applications in humans, it is necessary to fabricate TENGs with shapes that match the irregular contours of the human body, thereby advancing the development of conformal applications. Previously reported TENGs usually rely on the relative motion between two discrete compo...
