Description
Technical field
The present invention relates to a kind of preparation methods of large aperture nano fibrous membrane, belong to electrostatic spinning field.
Background technology
Electrostatic spinning technique is the simple effective method for being commonly used to prepare nano level superfine fiber at present, and principle is poly-
Polymer solution or melt overcome surface tension under high voltage electrostatic field, form injection stream, and super drawing refines, solvent is waved
Hair, cures and collects on the reception device, obtain electrostatic spinning fiber net.Due to the size of electrostatic spinning superfine fibre so that fine
Tieing up net has higher specific surface area and high porosity, can have in field of tissue engineering technology very big with bionical natural ECM
Application potential.The primary goal of tissue engineering bracket is that the function of cell ECM is realized in a three dimensions, guides surrounding tissue
With the migration and growth of cell, or to plant the growth of cell in holder porous structure suitable environment is provided, guarantee cell
Stick, rise in value, break up and migrate, and natural ECM is mainly by the azelon weave in shape of tens to hundreds of nanometers
At network structure.Therefore, the nanometer fiber net prepared with electrostatic spinning can effectively carry out ECM bionical.There are Many researchers
Natural or synthetic biomaterial is directly produced into the tubular structure material of different bores, research card by electrostatic spinning technique
Bright, a variety of mammalian cells such as endothelial cell, smooth muscle cell and fibroblast and human adult cell can be very
The good electrostatic spinning fiber that is attached on is online, and grows, is proliferated on it.Fiber prepared by electrostatic spinning due to ultra-fine fineness,
So that the web hole that fiber is formed after random alignment on the reception device is too small, and fiber gets over the hole between fine fibre
Gap will be smaller.Hole (being less than 1 μm) between nano level fiber has been far smaller than the size (10~100 μm) of cell, from
And block cell growing into internal stent, i.e. cell can only be grown in rack surface, be rised in value, and real meaning can not be formed
On three-dimensional rack, the formation of three-dimensional tissue is influenced, to affect application of the electrostatic spinning in this field.It is quiet in order to solve
The small problem of electrospinning fibre mesh gap has various methods to be used to the pore size of control electrostatic spinning fiber net in recent years.
Currently, common method has percolation, photoetch method, micro nanometer fiber composite algorithm and change reception device method etc..Wherein, it drips
Time-consuming for filter method, complex process；Photoetch method using laser ablation because can damage fiber；Micro nanometer fiber compound rule can be because
Reduce the specific surface area of fiber for coarse-fibred addition.Therefore, how to expand the mesh of fibrous framework becomes holder preparation
Urgent problem to be solved in the process.
