Embodiment 1

[0037] 1. Materials

[0038] Polyglycerol sebacate (the PGS) glycerol (99.5%, Sigma-Aldrich) and sebacic acid (99%, Sigma-Aldrich) polycondensation. Salt particles were purchased from Shanghai Chemical Reagent China. Carbon nanotubes (of CNTs) available from J & K Technology Co., Ltd. (99.9%, diameter: 5-10nm, outer diameter: 10-20nm, length: 10-30μm).

[0039] 2. Preparation of composite samples

[0040]① sebacic acid recrystallization. First, take a water bath heated to sebacic acid necked flask, setting means 78 ~ 80 ℃, then diethyl ether was added until dissolved sebacic acid, sebacic acid was completely dissolved after the solution was removed, cooled to room temperature, filtered off with suction. The above process is repeated three times, the last suction sebacic acid obtained was poured into an evaporating dish (aluminum pads), the cover foil (punching), at 60 ℃, dried in vacuo, to give complete recrystallization of sebacic acid .

[0041] The synthesis ②PGS. First of seba...

Abstract

The invention relates to a poly(glyceryl sebacate) 3D printing nanogenerator and its preparation method and application. After mixing poly(glyceryl sebacate) PGS, carbon nanotubes CNTs and a porogen, the generator is regenerated by 3D printing. It is obtained by thermal cross-linking and dissolution of porogen. The invention has good elasticity and conductivity. The use of 3D printing technology not only simplifies the preparation process of most flexible integrated TENGs, but also enables TENGs to be processed into complex and changeable three-dimensional structures, making the design of their shapes More diversity and flexibility, thus promoting the further development of flexible and integrated 3DP‑TENG on wearable electronic devices.

Description

Technical field [0001] The present invention belongs to the field of nano-generators, and more particularly to a poly (glycerol sebacate) 3D printing and nano-generators preparation method and application. Background technique [0002] Wang Zhonglin team first reported friction nano-generator (TENG), which can generate electricity electrification by friction and electrostatic induction phenomena, it has become mechanical energy from body movement and detects physiological activity of the new paradigm. Due to low cost, flexible design, the advantages of diversification of raw materials, TENG in academia and industry have made rapid progress. Considering the potential applications of humanity, people need to create TENG have irregular shape and contour of the body to match, so as to promote the development of conformal applications. Previously it reported TENG typically rely on relative movement between two discrete elements, which makes the assembly more complex TENG. This complex...
