Abstract
The invention discloses a kind of preparation methods of nanocomposite, belong to field of new materials.It is nano material and the substance that can sublimate that it, which is formulated, and processing step is：(1) first nano material is distributed in air；(2) heating and gasifying generator makes the substance of sublimating of solid phase or liquid phase become steam, and steam mixes under the traction of air-flow with the nano material being distributed in air, forms the mixture of nano material and the substance steam that can sublimate；(3) nano material passes through generator of sublimating with steam under air-flow traction, rapidly sublimates on generator sublimating.Avoid nano material that secondary agglomeration, the method for being directly compounded to form composite material with the substance that can sublimate occurs the invention has the advantages that providing one kind.
Description
Technical field：
The present invention relates to field of new materials, more particularly to a kind of preparation method of nanocomposite.
Background technology：
Nano material refers at least one-dimensional range or substantially single by their conducts in nanoscale in three dimensions
The material that member is constituted, in the range of nanometer scale, the various confinement effects of material can cause various characteristics generation quite big
Change, these variations can improve the comprehensive performance of material, condition is created for Development of Novel high performance material.However it is single
One nanocrystalline material has difficulties in technology of preparing, tends not to the needs for meeting practical application, many to study nanometer
Particle and other materials are combined into nanocomposite, and this composite material is possible to take into account nano-particle and other materials simultaneously
The advantages of, there is special performance.
Since nano-component grain size is small, large specific surface area, larger-size aggregate is easily formed, it is nano combined to make
It is not present in material or there are seldom nanometer phases, it is difficult to play the unique effect of nanometer phase.Therefore, nano-component is in the base
Dispersion be the key that prepare nanocomposite, widely paid attention to, at present realize nano-dispersion method have ultrasound
Wavelength-division dissipates, mechanical agitation is disperseed, dispersant disperses, chemical modification is disperseed etc..But these methods have dispersion effect difference or
It is the defects of destroying nano material integrality, difficulty reaches needed for relevant industries production.
The preparation of nanocomposite is to study the basis of nanocomposite performance and its application, and preparation method is always
It is the research hotspot in the field, preparation method has colloidal sol-suspension mixing method, graft process, blending method, sol-gel method, machine
Tool alloying, coating precipitation method etc..Above-mentioned preparation method is carried out based on the dispersion of nano material, is being prepared
Part nano material is still had in journey to reunite.
Invention content：
In view of the above shortcomings of the prior art, avoid the nano material after dispersion that secondary group occurs the present invention provides a kind of
It is poly-, and the method that can largely prepare nanocomposite.
The technical solution adopted in the present invention is：A kind of complex method of nano material, formula are nano material and can
It sublimates substance, the substance of sublimating is vapor, other substances that can be sublimated can also be used.If using vapor as can coagulate
Magnificent substance mixes nano material with vapor with certain proportion.
Its preparation process includes the following steps：
(1) first nano material is distributed in air；
(2) heating and gasifying generator makes the substance of sublimating of solid phase or liquid phase become steam, while steam leading in air-flow
The effect of drawing is lower to be mixed with the nano material being distributed in air, forms the mixture of nano material and steam；
(3) mixture of nano material and steam exists under air-flow traction by generator of sublimating, the steam for generation of gasifying
It sublimates and rapidly sublimates on generator, the nano material being distributed in air is transferred in solid solvent by this process, is avoided point
Nano material after dissipating is in direct contact with one another, and secondary agglomeration occurs.
Avoid nano material that secondary agglomeration occurs the invention has the advantages that providing one kind, while a large amount of prepare is received
The method of nano composite material.
Description of the drawings：
Attached drawing 1 is the production technological process of the present invention.
Specific implementation mode：
1 the present invention will be further described below in conjunction with the accompanying drawings, specific implementation：
The technical solution adopted in the present invention is：A kind of complex method of nano material, formula are nano material and can
It sublimates substance, the substance of sublimating is vapor, other substances that can be sublimated can also be used.If using vapor as can coagulate
Magnificent substance mixes nano material with vapor with certain proportion.
Its preparation process includes the following steps：
(1) first nano material is distributed in air；
(2) heating and gasifying generator makes the substance of sublimating of solid phase or liquid phase become steam, while steam leading in air-flow
The effect of drawing is lower to be mixed with the nano material being distributed in air, forms the mixture of nano material and steam；
(3) mixture of nano material and steam exists under air-flow traction by generator of sublimating, the steam for generation of gasifying
It sublimates and rapidly sublimates on generator, the nano material being distributed in air is transferred in solid solvent by this process, is avoided point
Nano material after dissipating is in direct contact with one another, and secondary agglomeration occurs.
Claims (1)
1. a kind of preparation method of nanocomposite, it is characterised in that：Formula is the nano material being scattered in air and can
It sublimates the mixture of substance, steps are as follows for the preparation method：
(1) first nano material is distributed in air；
(2) heating and gasifying generator makes the substance of sublimating of solid phase or liquid phase become steam, while steam is made in the traction of air-flow
It is mixed with nano material that is being distributed in air with lower, forms the mixture of nano material and steam；
(3) mixture of nano material and steam is being sublimated under air-flow traction by generator of sublimating, the steam for generation of gasifying
It rapidly sublimates on generator, the nano material being distributed in air is transferred in solid solvent by this process, after avoiding dispersion
Nano material be in direct contact with one another, and secondary agglomeration occurs；
Product is the solid-phase mixture of nano material and the substance that can sublimate, and product is the mistake of gradual " growth " sublimating on generator
Journey.
