Description
Technical field
The present invention relates to technical field of nanometer material preparation, in particular relate to three function Janus of anisotropic conductive magneto-optic
Nanofiber array film and preparation method thereof.
Background technology
Anisotropic conductive film is a kind of novel electronic component interconnecting material, it have one direction on electric conductivity and
Insulating properties on other directions, be widely used in Electronic Packaging, chip is fixed and electrode bonding etc. fields, cause
The great attention of people.
Simple function applications to nanostructures is limited in scope, and difunctional or multi-functional nanometer material application range is more
Extensively, this kind of material has more characteristic and attraction, and therefore, multi-functional nanometer material is paid high attention to by researcher.With nanometer
The development of science and technology, nano material such as have the characteristics of luminescence, electric conductivity or magnetism, towards difunctional and more work(by simple function
Can direction develop, such as have the function of magneto-optic, photoelectricity or electromagnetism be difunctional and photoelectromagnetic three, in this way can be in a kind of nanostructure
Difunctional or three functions are realized on material, are had to the development of nano-device, nanotechnology and relevant science and technology important
Meaning.For example, magnetism-fluorescent dual-function nanocomposite provides a kind of new platform for medical diagnosis on disease and treatment, due to
Their difunctional property makes " it was found that-detection-treatment " of disease to be integrally formed.The use of this nanocomposite will be into one
Step improves the efficiency of diagnosis and reduces side effect, causes the highest attention of researcher.Electromagnetism dual-functional nanometer compound is in thunder
It has broad application prospects up to wave absorption, electromagnetic shielding, antistatic coating and sensor etc..
Janus materials refer to two kinds of chemical compositions or a kind of chemical composition but structure difference has clearly in same system
Partitioned organization, thus there is double properties such as hydrophilic/hydrophobic, polar/non-polar, shine/conductive, horizontal direction is conductive/vertical
Direction conduction etc. is one of forward position, hot research direction of materials science field.The Janus nanofibers of document report at present
All be made of shoulder to shoulder and together the different nanofiber of two chemical compositions, tool there are two specific partitioned organization and
Two or more property, as the side nanofiber of Janus nanofibers has lighting function, other side nanofiber
With conductive and magnetic function, then this Janus nanofibers have the function of to shine, are conductive and magnetic three.
