Abstract
The invention relates to a method for preparing a fiber material by use of self-curling of a polymer film. In the method, a novel fiber material is prepared by performing controllable self-curling of a patterned poly-4-vinylpyrimidine film in an acid aqueous solution; before curling, the polymer film is treated by different surface treatment technologies (such as plasma chemical activation, metal sputtering, nano particle deposition and the like), the film is unidirectionally cut with scratches by a metal blade at an interval of hundreds of microns, the curling starts from parallel scratches, and biaxial fiber is formed finally. According to the method provided by the invention, 1cm<3> of fiber material can be produced on every 50cm<2> of patterned film, thus the yield of the fiber material is increased, and the method has large-scale industrial application prospects.
Description
Technical field
The present invention relates to a kind of preparation method of novel nano fiber, relate in particular to a kind of thin polymer film of patterning that utilizes from the curling method of preparing fibrous material.
Background technology
The fibrous material with advanced function has application very widely in fields such as medical science, Chemical Engineering, cyto-dynamics, intelligent fiber and products thereof can be developed to the container discharging for the timbering material of biological tissue regeneration, controlled medicine, member element, sensor and the opto-electronic device etc. of electroactive artificial muscle.In most application, the advanced function of functional fibre depends on its complicated structure and accurate fabrication schedule.Electroactive fiber is by conducting polymer, the continuous shell that electrolyte and electrode form forms, the fiber with hollow-core construction can utilize the method preparation of core-shell electrostatic spinning, or by preparing in the method for inside deposition polymer with the template film of microcellular structure.This fiber has application very widely as drug delivery, catalysis and infrared conduction.
Being widely studied in recent years for a kind of micron or the wide tubulose of sub-micron and method of reel material prepared from curling of micro-oriented film with different natural qualities; Be accompanied by wrinkling and expand, the lax pattern of the face internal pressure of a kind of inside of curling formation of film, has the polyphasic film of structure for what depart from substrate that curling right and wrong are usually shown in conventionally; For polymer, heterogeneity has relation from the top of film and the different chemical composition of outside.In prior art, the research of exploitation aspect of fibrous material that is attached with functional micro-nano granules is less, and the output of this fiber material is very low.
Summary of the invention
The present invention has prepared a kind of novel fibrous material, this material be utilize to stimulate corresponding type polymer as crosslinked poly--micro-curling preparation of 4-vinyl pyrimidine, micro-curling be by patterned process in the wide striped of submillimeter poly--certainly the curling into of the film of 4-vinyl pyrimidine.Carry out curling before, thin polymer film can be processed with different process for treating surface (as plasma chemistry activates, metal sputtering, nanoparticle deposition etc.).The present invention shows, from curling program, can be used for developing the polymeric fibre material that a large amount of preparations have reel internal structure, also prepares magnetic micrometer particle (Fe
