Abstract
The invention discloses a solvent-free inorganic nanometer particle fluid and preparing method, which comprises the following parts: nanometer silicon dioxide, nanometer ferric oxide, nanometer calcium carbonate, nanometer titanium dioxide and nanometer soot carbon, wherein the longchain structure of organosilicone quaternary ammonium salt and electrostatic repulsion action make the inorganic nanometer particle have liquidity in solvent-free state.
Description
Technical field
The present invention relates to inorganic nano-particle process for modifying surface field, be specifically related under condition of no solvent, to have the inorganic nano-particle technology of class fluid behavior in the organosilicon quaternary ammonium salt preparation of inorganic nano-particle surface grafting long-chain.
Background technology
Nano material is the novel material that grows up the eighties in 20th century, from a birth, just is described as " the most promising material of 21st century " by U.S. material association because of application prospects.Nanoparticle is by number less atom or molecular former subgroup or molecular group, and its surface atom is the amorphous layer that had not only had long-range order but also do not had short-range order; And in particle heart portion, the atom that exists complete crystallization periodically to arrange.Because this special structure of nanoparticle makes nano material have characteristics such as special surface effects, volume effect, quantum size effect and macro quanta tunnel effect, and produces the different physicochemical property of many and conventional solid thus.But when having these excellent properties, because nano-particles size is very little, surface energy makes it to reunite easily greatly.After inorganic nano-particle is reunited, can destroy a lot of excellent performances of nano material.Therefore must carry out surface treatment to inorganic particulate when using, with primary partical or stable than small agglomerates, stoping reunites takes place.
It is a lot of at present inorganic nano-particle to be carried out the surface-treated method, according to having or not chemical reaction between surface treatment agent and the particle, can be divided into absorption parcel modification and surface chemical modification two big classes.Absorption parcel properties-correcting agent commonly used is generally macromolecular material, as macromolecule dispersing agent.The static of the active functional group of containing by functional group on the macromolecule dispersing agent or nanoparticle surface layer forms parcel in conjunction with making dispersion agent be fixed on particle surface, and the method for employing mainly contains two kinds: (1) in solution or melt polymer deposition, be adsorbed onto the modification of particle surface parcel; (2) monomer absorption parcel post polymerization.Surface chemical modification then can produce stronger interaction force between modifier and nanoparticle.Chemically treated method mainly contains three kinds: (1) surfactant method.Organo-functional group that utilizes tensio-active agent etc. carries out chemisorption or chemical reaction with particle surface, makes tensio-active agent be covered in particle surface; (2) plasma body and radiation-initiated polymerization modification.With methods such as high-energy radiation, Cement Composite Treated by Plasma, inorganic particulate surface bonding hydroxyl is produced have the spike trigger monomer of initiating activity at its surface aggregate; (3) particle surface graft polymerization modification.But by connect the organic group of direct polymerization, the perhaps treated organic group various polymkeric substance on the inorganics surface grafting that produce free radical in inorganic particles surface linked reaction.
The surface modifying method of these above-mentioned nanoparticles has solved nanoparticle substantially owing to surface energy causes from the problem of reuniting, and preferably resolve the compatibility problem of inorganic nano-particle and macromolecule matrix, in inorganic/polymer composite, be widely used.But a common issue with of these method of modifying is still to exist with solid-state under condition of no solvent through inorganic nano-particle after the modification.Inorganic nano-particle under this solid state usually as applying filler in the polymer/inorganic nanometer particle composite material; In other field, in the self-assembly application as nanoparticle, inorganic nano-particle must add solvent to be used, and the inorganic nano-particle strength of fluid is up to 50% sometimes.Therefore this solid-state inorganic nano-particle Application Areas has been subjected to very big restriction.If inorganic nano-particle has the fluidic flow behavior under condition of no solvent, can greatly widen the application of inorganic nano-particle undoubtedly, but the research of at present relevant solvent-free inorganic nano particle fluid yet there are no report at home and abroad.
Summary of the invention
The object of the present invention is to provide a class under condition of no solvent, to have the inorganic nano-particle of fluid behavior, and the preparation method of this solvent-free inorganic nano particle fluid is provided.
The inorganic nano-particle that the present invention relates to comprises nano silicon, nano-sized iron oxide, nano-calcium carbonate, nano titanium oxide and nanometer carbon black.
For achieving the above object, the present invention carries out surface modification at the organosilicon quaternary ammonium salt of inorganic nano-particle surface grafting long-chain to inorganic nano-particle.Making inorganic nano-particle have flowability under solvent-free state by the backbone of organosilicon quaternary ammonium salt and the Coulomb repulsion effect of organic ion salt, is the solvent-free inorganic nano particle fluid of a class.This solvent-free nano particle fluid, be different from traditional nano-particle solution, it is a kind of monophasic, solvent-free colloidal materials, a large amount of organic long-chain of surface grafting has good flexibility, be easy to flowing of inorganic nano-particle, the electrostatic force of long-chain gegenion makes inorganic nano-particle possess flowing property under condition of no solvent under interacting simultaneously.This solvent-free inorganic nano particle fluid not only can the same nano composite material that is applied to the solid-state inorganic nano-particle of routine, realization is to toughness reinforcing, the enhancing of macromolecular material, can realize the self-assembly of nano material as the inorganic nano-particle that adds solvent simultaneously; And this solvent-free inorganic nano particle fluid represents more great application prospect in fields such as the plasticising of high temperature lubricating, emr fluid, ionic exchange film for fuel cell, macromolecular material and new reaction media.
