Description
Technical field
The present invention relates to a kind of preparation methods of colorimetric strain gauge based on Ag nanoparticle assemblies, in different drawings
The variation that macroscopical color may be implemented under power and pressure effect, can become yellow from blue, belong to intellectual material field.
Background technique
Noble metal nanometer material relies on its stronger plasma resonance characteristic, has stronger absorption to visible light,
Thus show different colors.Surface plasma resonance (SPR) characteristic of noble metal nanometer material depends primarily on material
Size, pattern and dielectric constant.In addition, the coupling between adjacent particle is same in noble metal nano particles assembly
It can produce stronger plasma resonance effect, plasma resonance effect may be implemented by the regulation between spacing particle
The regulation answered, and then obtain the assembly that different colours are macroscopically presented.Currently, grinding about noble metal nano particles assembly
Studying carefully has extensive use in all various aspects, such as：Surface enhanced Raman technique, color identifier, biological therapy, chemical detection
With sensor etc..Also there are many patent documents to report simultaneously, such as：Chinese patent document CN106415196A discloses one
Colorimetric strain gauge of the kind based on plasmon, Au nanoparticle assemblies are dispersed in PVP and prepare film forming, not
Different colours can be presented under same pressure.However, the preparation based on noble metal assembly function element focuses primarily upon Au and receives
Rice grain assembly, still has several drawbacks at present.Firstly, Au low memory, expensive, higher cost；Secondly as Au
The limitation of nano particle itself plasma resonance characteristic becomes so Au nanoparticle assemblies can only be become red from blue
Color range is narrow, is unfavorable for visually applying.
Therefore, price is lower, the wider array of power of color change interval causes color-changing membrane for exploitation, becomes this field technology urgently to be resolved and asks
Topic.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of colorimetric strain gauge based on Ag nanoparticle assemblies
