Abstract
The invention discloses a kind of preparation methods of the function textile of doping N Au titanium dioxide nano threads, are related to a kind of preparation method of the function textile of doping N Au composite titanium dioxide nano wires.The mixed solution of butyl titanate and ethyl alcohol is added in the aqueous solution of slant acidity, it is gel to wait for that it hydrolyzes to form colloidal sol and is aged.Using NaOH provide alkaline condition change titanium dioxide surface hydroxyl distribution, Hyperbranched Polymer with Terminal Amido be complexed reducing metal ion, make its on the fabric oriented growth and obtain doping N Au composite titanium dioxide nano wires function textile.The present invention utilizes the synergistic effect of NaOH and Hyperbranched Polymer with Terminal Amido, controls the morphology and size of nano material, realizes the function textile that one step hydro thermal method prepares doping N Au composite titanium dioxide nano wires.This complex method is simple, and uniform doping on the fabric.
Description
Technical field
The present invention relates to a kind of preparation methods of function textile, more particularly to a kind of to have photocatalysis performance, uvioresistant
The preparation method of the function textile of the doping N-Au composite titanium dioxide nano wires of performance and anti-microbial property.
Background technology
Nano-titanium dioxide has high catalytic activity, good as important inorganic transition metal oxide material
Against weather, excellent anti-uv-ray.In recent years, the research of titanium dioxide nano material is growing day by day, at waste water
The fields such as reason, sun-proof skin care, coating and sensor, photochemical catalyst receive the concern of people.Compared to other transition metal oxides,
Nano-titanium dioxide can absorb ultraviolet light, reflection ultraviolet light, can also penetrate visible light, before being superior performance, great development
The ultra-violet protecting agent on way.Numerous studies show compared to titanium dioxide nanoparticle, the specific surface area of titanium dioxide nano thread
Bigger, surface electronic transmission speed faster, it is wider using area.But pure nano-titanium dioxide semi-conducting material is as catalyst
It comes with some shortcomings：Be first itself energy gap it is wider (Eg=3.2ev), it is ultraviolet less than 387nm to be only capable of absorbing wavelength
Light, and the visible light to being in the great majority in sunlight does not act；The recombination probability of followed by electron-hole is big, effectively
The photon time-to-live is short, quantity is few so that nano-titanium dioxide can not give full play to its catalytic.
In order to improve application of the nano-titanium dioxide in photocatalysis field, a large amount of report displays, to nano-titanium dioxide into
Row doping is a kind of effective ways to the absorption of visible light to reduce its energy gap or improve.Doping method is related to metal and non-
Metal-doped, ion doping, semiconductors coupling and surface modification etc., wherein precious metal doping effect is best, and doping approach includes
Ultraviolet photoreduction met hod, chemical reduction method and electrochemical deposition method etc..After nano-titanium dioxide light excitation after modification, valence band
The electronics of middle generation flows to the lower metal of Fermi's energy so that the separation of light induced electron and hole improves quantum efficiency, in turn
Improve the photocatalysis performance of nano-titanium dioxide.Common metal is doped with Pt, Ag, Pd and various rare metals, metal ion
And metal oxide, but the metal-doped utilization rate to visible light is still relatively low.Based on nonmetal doping is mainly adulterated with N, but N
Doping also easily causes the compound of electrons and holes, reduces photocatalysis efficiency.Therefore, metal and nonmetallic co-doped are utilized

It is first to prepare titanium dioxide granule, then titanium dioxide nano thread is made through alkaline condition hydro-thermal.Nanometer made from these methods
Size, Size Distribution and the reaction condition of titanium dioxide granule directly affect titanium dioxide nano thread surface topography and
Dimensional homogeneity, and the energy consumption of this two-step synthesis method is higher, seriously polluted, does not meet low energy consumption, " green " production requirement.
The photocatalytic of modified nano-titanium dioxide is also related with the state of dopant, structure, content, distribution etc..Such as mix
When miscellaneous gold simple substance, golden simple substance catalytic activity is influenced by nanogold particle size, load capacity etc..Studies have shown that when gold
When particle size ＜ 10nm, higher catalytic activity is shown；When golden simple substance load capacity ＜ 5%, it is easier to obtain small size
Gold particle.In addition, the specific surface area of nano-titanium dioxide and also influencing composite catalyst with the interaction of gold particle
Activity.When load capacity is excessive, the compound of electrons and holes is accelerated instead, reduces catalytic efficiency.To sum up, in loaded metal particle
In the process, the size of metallic particles and the controlled distribution on nano-titanium dioxide are particularly important.
Titanium dioxide nano thread is evenly affixed to fabric surface, and fabric may make to obtain photocatalysis performance, uvioresistant performance
And anti-microbial property.Present invention process is simple, can reach certain washable index, and fabric is made to obtain durable finish effect, this
Also will be the key that nano-function textile development and application.
