Embodiment 1
[0047] Embodiment 1. Preparation of self-healing liquid metal flexible electronic materials and circuits of the present invention
[0048] figure 1 It is the preparation process of the self-repairing liquid metal flexible electronic material and circuit of the present invention.
[0049] (1) Preparation of substrate
[0050] Put 30g of α-lipoic acid, 10g of butyl acrylate, and 10g of acrylic acid into a 250ml round-bottom flask and stir at 150°C to melt completely. After reacting for 3.5h, introduce it into a polytetrafluoroethylene mold and cool to form a transparent polymer substrate.
[0051] (2) Plasma treatment of substrates
[0052]Use computer-aided design according to the required circuit, process the metal template of the designed shape, use the metal template to selectively cover the polymer substrate, and use plasma to perform plasma treatment on the exposed part of the substrate. The gas flow rate during plasma treatment is 30L / min, the plasma power is 500W.
