Background technology
It is liquid metal near room temperature that liquid metal typically refers to a kind of, as the gallium of fusing point less than 30 DEG C or its alloy, also or in slightly higher temperature range as 40 DEG C-200 DEG C periods can present the low-melting point metal alloy of liquid state as materials such as bismuth indium tin zinc.In the past, due to all multiattributes of liquid metal and purposes rarely known by the people for a long time, this large class functional materials is less is subject to academia in global range and industrial community is paid attention to.In recent years, along with obtaining of a series of major progress, the significant application value of liquid metal progressively draws attention.In a variety of applications where, liquid metal material is owing to can liquid states of matter work, and mobility is fine, and itself has natural electroconductibility, thus be introduced in emerging printed electronic in recent years, functional device 3D print field, become unique important can printing-type electronic material.
But, existing liquid metal limit due to himself physical property or alloy composition, self gloss of the liquid metal formed is silvery white in color mostly, color is very single, this much requires higher printing or application of paints occasion to color and aesthetic measure for industrial, to form the aesthetic conceptions of circuit and people apart from each other.In fact, along with the raising of social development and material and cultural life, for many new electronic and consumption electronic product, user is no longer only satisfied with and obtains its basic electrical functions, the color embodied for product and experience and also propose heavy demand.To a great extent, color determines effect of many products really.Ever-changing and the form and aspect of nature color, constitute the riot of colour, the multicoloured world.Say from Psychological Angle, different colours can cause different senses to look to human body, such as: soft, bright colors, and can with giving happiness, the beautiful enjoyment such as happy, relaxed and joyful; Otherwise the even extreme embodiment of color imbalance then can allow people feel dull, lose heart, even have influence on physical and mental health.
Regrettably, up to now, liquid metal printed electronic ink itself developed in recent years there is no method and presents color function, more difficultly reaches the ever-changing of color.Obviously, if its color function can be given to the liquid metal principle with printability, will greatly promote its special performance, realize coloury printed electronic or the making of 3D metal thus, then significantly strengthen experience sense and the artistic value of product.For this reason, the present invention proposes the technological concept of color liquid metal first, and its object is just being to provide liquid metal with various color and preparation method thereof, to the existing technology category of take on a new look existing liquid metal and pigment.
We know, pigment refers to the material that object can be made to catch color, and the mankind know use pigment very early, as utilized coloured soil and ore, crag being drawn a picture and smears health.Equally, for making liquid metal can also present bright-colored color while maintenance electroconductibility and mobility, the invention provides pigment and loading measure, by the preparation of specific pigment and liquid metal, the liquid metal of color of all kinds can be obtained.
In view of this, special proposition the present invention.
