Structure, it is easy to operate when placing and taking out transparent membrane 2.
In a specific embodiment, it is flat that the top plate 1a and bottom plate 1b of fixture 1, which are formed by the shape of hollow structure,
Face, concave surface or convex configuration, the shape for being packaged with the transparent membrane 2 of liquid metal 3 is also accordingly plane, concave surface or convex surface are tied
Structure, the then transparent membrane 2 for being packaged with liquid metal 3 being fixed in fixture 1 form plane mirror, concave mirror or convex mirror.
The material of fixture 1 is transparent glass or clear hard plastics.Fixture 1 is transparent material, will not influence liquid metal 3
Metallic luster, high light-reflecting property, to will not influence mirror effect.Glass or rigid plastics have certain intensity, can
Make the fixed form of the transparent membrane 2 for being packaged with liquid metal 3, forms the mirror surface with specific shape.
Liquid metal 3 is low-melting-point metal.Low-melting-point metal has the distinctive metallic luster of metal material and high reflective spy
Property, while its smooth surface, and have the characteristics that nontoxic, property is stable.Using low-melting-point metal as the material for preparing mirror surface
Material, using its metallic luster, high light-reflecting property and mobility, convenient for preparing the mirror surface of arbitrary shape.
The low-melting-point metal that liquid metal 3 uses is bismuth-base alloy or indium-base alloy.
In a specific embodiment, bismuth-base alloy be 35% bismuth, 49% indium and 16% tin composition bismuth indium
Tin alloy；The indium stannum alloy that indium-base alloy forms for 76.5% indium and 23.5% tin.It is shown in Figure 6, in routine use
In the process, which exists in the form of solid, together with transparent membrane 2, mirror surface of the formation with specific shape, such as with
Plane, concave surface or the mirror surface on convex surface.
But since the fusing point of the alloy is lower, after being heated with heater circuit 5, liquid can be become from solid-state quickly, just
In the shape for changing existing mirror surface, being formed has new mirror surface of different shapes.Simultaneously as the fusing point of the alloy is lower, when
When heater circuit 5 heats liquid metal 3, temperature when liquid metal 3 melts will not be to the transparent of encapsulation liquid metal 3
Film 2 generates adverse effect.
Transparent membrane 2 is highly elastic material.The highly elastic material is capable of forming the structure of arbitrary shape, such as with flat
The structure in face, concave surface or convex surface.Since the liquid metal 3 being encapsulated in transparent membrane 2 is in a liquid state, there is good mobility,
The transparent membrane 2 for being packaged with liquid metal 3 is also capable of forming the structure of arbitrary shape, such as with plane, concave surface or convex surface
Structure.
The highly elastic material that transparent membrane 2 uses is silicon rubber, or contains dimethyl silicone polymer class, polyphenyl dioctyl phthalate
One of two esters of second, polyvinyl alcohol, polyvinyl formal class or polyvinyls are a variety of.Such material is light
It is transparent, nontoxic, non-corrosive, during making mirror surface, there is good tolerance, transparent membrane 2 uses the time long
Long.
In addition, transparent membrane 2 has very high transparency, the liquid metal 3 being encapsulated in transparent membrane 2 will not influence
The effect of metallic luster, high light-reflecting property, to make the mirror surface being prepared that there is good mirror effect.
A kind of deformable minute surface of the invention, including the liquid metal being encapsulated in the closed hollow structure of transparent membrane 2
3, the transparent membrane 2 for being packaged with liquid metal 3 is fixed in fixture 1, be bonded with the inner face of fixture 1 and row at in fixture 1
The mutually isostructural mirror surface in end face.
