This application relates to the field of flexible electronics technology, specifically to an ultrathin flexible electronic conductor material and its preparation method. The preparation method of the ultrathin flexible electronic conductor material is as follows: (1) adding conductive filler, dispersant and binder to deionized water, ultrasonically dispersing to obtain a conductive slurry, coating the conductive slurry on the surface of a flexible substrate layer, and drying and curing to obtain a flexible substrate layer with a conductive functional layer; (2) preparing a polyethylene terephthalate solution, coating the polyethylene terephthalate solution on the surface of the conductive functional layer, and curing to obtain the ultrathin flexible electronic conductor material. This ultrathin flexible electronic conductor material has low sheet resistance, high conductivity stability, excellent bending resistance and solvent resistance, and significantly improved tensile strength and elongation at break, exhibiting excellent mechanical properties, making it suitable for long-term reliable application of flexible electronic devices.

The invention provides a self-cleaning coating with high mechanical property and high adhesive force and a preparation method of the self-cleaning coating. The preparation method comprises the following steps: firstly, synthesizing polydimethylsiloxane-based polyurea (PDMS-PUa) with high light transmission through a solution mixing method; then, preparing CQDs by using an alkali-assisted ultrasonic method, and effectively loading and uniformly dispersing the CQDs in the PDMS-PUa under a continuous ultrasonic condition, so as to finally prepare the PDMS-PUa / CQDs material. According to the present invention, the strong hydrogen-bond interaction is formed between the polar group of the CQDs and the amino group of PDMS-PUa, such that the stability of the whole network structure is enhanced through the interaction, such that the mechanical property is improved, the adhesion property of the material is significantly improved, the adhesion of PDMS-PUa / CQDs can be improved to 3.1 MPa, and the tensile strength of 8.6 MPa and the elongation of 718.65% are provided. The introduction of CQDs also improves the surface tension characteristic of PDMS, promotes the uniform wetting of the coating material, effectively reduces the generation of bubbles and the occurrence of small hole phenomena, and also has better self-cleaning performance.
