Problems solved by technology

[0008] In order to overcome the shortcomings of the existing material technology and change the current situation that the traditional liquid metal has a single color and the traditional pigment does not have conductivity, the present invention provides a colored liquid metal material, which is obtained by loading the pigment itself in the liquid metal. The metal material of the desired color can be used to make colorful electronic circuits or 3D metal printing or more purposes, and the invention also provides a method for making the colored liquid metal

Abstract

The invention provides colored liquid metal and a manufacturing method thereof. A colored liquid metal raw material comprises a liquid metal body, pigment and/or nanometer conductive particles. The colored liquid metal can be presented in various specific colors while achieving electrical conduction. Firstly, the colored liquid metal has good electrical conductivity of liquid metal and rich colors of the pigment, an approach to color printed electronics can be opened up, and the aesthetic property and experience of the printed electronics can be remarkably promoted; meanwhile, the oxidation resistance and rust-proof property of traditional liquid metal are improved.

Description

technical field [0001] The invention belongs to the field of liquid metal materials, and in particular relates to a colored liquid metal and a manufacturing method thereof. Background technique [0002] Liquid metal usually refers to a metal that is liquid at room temperature, such as gallium or its alloys with a melting point below 30°C, or a low melting point metal that can be liquid at a slightly higher temperature range such as 40°C-200°C Alloys such as bismuth indium tin zinc and other materials. In the past, due to the long-term ignorance of many properties and uses of liquid metals, this large category of functional materials has received less attention from academia and industry around the world. In recent years, with a series of major developments, the important application value of liquid metals has gradually attracted attention. In various applications, liquid metal materials can work in a liquid state, have good fluidity, and have natural conductivity, so they ...
