Abstract
The invention provides a sheath-core composite photocatalytic fiber and a method for preparing the same. The method includes steps of placing sheath-core composite polyester fibers in composite photocatalyst solution and carrying out padding treatment on the sheath-core composite polyester fibers; sequentially carrying out first heat treatment and second heat treatment on fibers obtained by means of padding treatment so as to obtain the sheath-core composite photocatalytic fiber. The sheath-core composite photocatalytic fiber and the method have the advantages that composite photocatalysts can be firmly attached onto the sheath-core composite polyester fibers by the aid of the padding treatment, polyester of core layers can have certain viscosity after the fibers are subjected to the first heat treatment and the second heat treatment, and accordingly excellent adhesion effects can be realized for the composite photocatalysts; as shown by experimental results, the sheath-core composite photocatalytic fiber is high in sulfadiazine degradation rate, and all sulfadiazine can be degraded by the sheath-core composite photocatalytic fiber in 5 hours approximately; the sulfadiazine degradation activity of the sheath-core composite photocatalytic fiber is hardly changed after the sheath-core composite photocatalytic fiber is reused by 20 times, and accordingly the sheath-core composite photocatalytic fiber is excellent in photocatalytic stability.
Description
Technical field
The present invention relates to catalysis material technical field, particularly relate to a kind of core-sheath photocatalytic fiber and preparation side thereof
Method.
Background technology
Photochemical catalytic oxidation is the method for the energy-efficient degradation of contaminant of a kind of comparison, by utilizing sunlight, and can be complete
Degradation of contaminant entirely and effectively.Catalysis material is under the irradiation of light, utilizes being converted into of luminous energy that nature exists
Energy needed for learning reaction produces catalytic action, make the oxygen of surrounding and hydrone be excited into great oxidizing force freely bear from
Son, self does not change and but can promote the material that chemical reaction is carried out.
Catalysis material has antibiotic property, air cleaning, deodorization, mildew-resistant, anti-algae, the effect of anti-fouling and self-cleaning, almost separable
Solve all to human body and the organic substance of bad environmental and part inorganic substances.Meanwhile, catalysis material has high safety
Property, even can be as food and medicine additive, through U.S. food Drug Administration (FDA) certification, use the safest.
Simultaneously as catalysis material provide only the place of reaction, itself is also not involved in chemical reaction, and it is good lasting to have
Property.
Photocatalytic fiber is the one in catalysis material, and prior art typically uses modern complex technique by nano-silica
Change titanium and realize perfect adaptation with macromolecular material, then by melt spinning, nano titanium oxide can be uniformly distributed among fiber,
