Description

A kind of preparation method of mesoporous silicon dioxide spiral coil
One, technical field
The present invention relates to novel silicon dioxide spiral coil of a class and preparation method thereof, it belongs to the nano material preparation technical field
Two, background technology
At the synthetic artificially spirane structure material of Jie's sight aspect wide significance is arranged, not only because spirane structure and biological phenomena are so tight, and the spirane structure material also provides the performance more superior than common material.With regard to the carbon nanotube of spiral, early 1990s, the Motojima of Japan prepares the good helical carbon fiber of circulation ratio.Helical carbon fiber is except that excellent properties such as the thermotolerance that possesses common carbon fibers, chemical stability, electric heating conductivity, thermal expansivity and low density, also, be expected to become novel radio-radar absorber, little responsive energy absorber and Microspring and use because of its special spirane structure has typical chirality feature and good elasticity.
In recent years, the mesoporous SiO of micron order that forms for the basic comprising unit with the meso-hole structure 2Spiral tube is in the news successively.In general, the present mesoporous SiO of synthetic 2Spiral tube can be divided into two types: a kind of is that bigger product particle presents the helix structure, the macro morphology (micro-meter scale) that is product shows helix, and it constitutes elementary cell (mesoporous) and might not show orderly spirane structure, synthetic representative with seminars such as Ozin; Another kind is to constitute the mesoporous of macro morphology itself (nanoscale) also to show orderly spirane structure, work as the people such as Che of Nature in 2004 report, mesoporous pipeline shows consistent sense of rotation in its product, shows as the micron rifle bar with chirality on the macroscopic view; Stucky etc. also have similar report on NatureMaterials.
From the synthetic route, the synthetic method of these several typical mesoporous spiral tubes has nothing in common with each other, and is broadly divided into: (1) single template; (2) template adds physical action; (3) composite mould plate agent method; (4) soft or hard template.Wherein the mechanism [Che, S.et al.Nature2004,429,281] of composite shuttering has promptly been used in the work of Che seminar.
Mainly be by the charge effect between the adjusting template in the work of Che, thereby form spiral composite mould plate agent, detailed process is as follows: with the amino acid salts N-miristoyl-L-alanine sodium (C of 0.32g (1mmol) 14-L-AlaS) being dissolved in the 32g water under the room temperature, the back adds 1.4g (0.14mmol) 0.1molL -1Hydrochloric acid soln makes a part of acidifying in the amino acid salts, produces a certain amount of free amino acid (C 14-L-AlaA).Above mixing solutions stirred after 1 hour, added the N-trimethoxysilylpropyl-N of 1.4g tetraethoxy (TEOS) and 0.20g in mixing solutions, N, N-trimethylammonium chloride (TMAPS).In above mixed system, the ammonium positively charged of TMAPS, and C 14-L-Alas and C 14Hydrophilic the base band negative electricity of-L-AlaA, two kinds of template are assembled by the interaction of positive and negative charge and are become the composite mould plate agent with spirane structure, again by controlling the hydrolytic action of TEOS, make silicon-dioxide be coated on template uniformly, roasting finally obtains having the micron bar of foraminous spiral tract structure after 6 hours under 650 ℃ of air atmospheres.Though can make the spiral micron bar of comparison homogeneous by this route, exist also that some is not enough: (1) synthesis material (as amino acid salts) costs an arm and a leg, common lab synthetic still can, but be unfavorable for large-scale preparation; (2) aperture of gained sample less (2 ~ 3nm), be unfavorable for that the later stage duct modifies; (3) the foraminous spiral tract structure in the sample is single, only has one-level duct (2 ~ 3nm's is mesoporous) to limit its range of application.
We are by cheap raw material glucose, triblock copolymer, success synthesized a micron spiral tube, its complex structure, synthesis material is easy, and good prospects for application is arranged.
Three, Fa Ming content
Purpose of the present invention: a kind of new preparation method is provided, prepares three grades of self-assembly mesoporous silicon dioxide spiral coils with it.One-level hole: mesoporous (10nm); Second hole: by the mesoporous solenoid coil (70nm) that constitutes for wall; The micron spiral tube that three grades of holes: by second hole---solenoid coil constitutes.It is expected to be applied in the aspects such as processing of complicated nanometer, micron devices.
Principle of the present invention is as follows: the extent of polymerization of at first controlling glucose, obtain this elementary template of bunching sugar, again under strong acidic condition, pass through interaction of hydrogen bond by polymer neutral surface active agent and bunching sugar, form senior template, add the silicon source therein, make its hydrolysis under given conditions, be coated on the template surface uniformly, roasting obtains three grades of mesoporous silicon dioxide spiral coils later on.
The object of the present invention is achieved like this: with 100gL -1D/W place 160 ~ 190 ℃ to keep 3 ~ 6 hours down, obtain the bunching sugar aqueous solution; With bunching sugar aqueous solution and poly-oxyethylene ether-poly-propylene oxide ether-poly-oxyethylene ether three block macromolecular polymeric surfactants (molecular-weight average 5800) (writing a Chinese character in simplified form P123) and 2molL -1Hydrochloric acid soln mixes mutually, adds tetraethoxy; 100gL -1D/W, poly-oxyethylene ether-poly-propylene oxide ether-poly-oxyethylene ether three block macromolecular polymeric surfactants (molecular-weight average 5800), 2molL -1Weight ratio between several reactants of hydrochloric acid soln and tetraethoxy is 40 ~ 60: 1: 30 ~ 50: 2 ~ 3; Treat that the abundant hydrolysis of tetraethoxy is placed in the encloses container, be heated to 160 ~ 190 ℃, be incubated 24 hours; Product is after separation, washing, drying, and 550 ~ 650 ℃ of roastings are 6 ~ 8 hours under air atmosphere, after reduce to room temperature and obtain three grades of self-assembly mesoporous silicon dioxide spiral coils.
