Many soft tissues in organism equally maintain many common ground, but biologic soft tissue show good flexibility,
The advantages that selfreparing and excellent mechanical property, traditional hydrogel but generally existing bad mechanical property the problem of, it is difficult to from
The defects of reparation, so that greatly limit hydrogel material obtains practical application in wider field.
The pursuit that the intrinsic self-repair function of material is material scholar is assigned, self-repair material can undoubtedly increase substantially
Materials'use service life and the security and stability used.One of recent years, the main application as hydrogel, it is by significantly
Applied to flexible electronic field, based on macromolecule hydrogel, the flexibility, stretchable and review one's lessons by oneself of hydrogel material is made full use of
The advantages that multiple, as substrate, new such as flexible super capacitor and flexible electronic skin are constructed, has become flexible electrical
One hot research field of subdomains.For example, Zhigang Suo etc. coat a large amount of electrolyte using hydrogel, one is prepared for
The high stretching hydrogel based sensor of kind (Advanced Materials, 2014,26 (45), 7608.).Chunyi Zhi etc. are utilized
It is a kind of a kind of stretch and the multiple flexible super capacitance of selfreparing can to have been constructed with the hydrogel material of the high stretching of selfreparing
Device (Nature communications, 2015,6,10310.), in its subsequent work, by prioritization scheme, in one kind
On hydrogel basis with Ultra-Drawing rate, a kind of flexible super capacitor that can stretch ten times has been constructed
(Angewandte Chemie International Edition,2017,31,9269.).These materials, will realize high stretching
And selfreparing, some special designs are required for, the water-setting glue material of high stretching selfreparing how is prepared with simple one-step method
Material, has great importance in many research fields particularly flexible electronic field.
In the past more than ten years, scientists develop all polymorphic type hydrogels, and height stretching selfreparing hydrogel is also
The hot spot of one of research, in this kind of material developed in the past, is largely all based on the cross-linked form of non-covalent bond
Come the hydrogel network constructed, such as polyvinyl alcohol hydrogel based on hydrogen bond has self-healing properties, based on nano-sheet material
Material such as clay (Macromolecular Rapid Communications, 2011,32 (16), 1253.) or graphene oxide
The drawing that the hydrogel material that (Chemistry of Materials, 2013,25 (16), 3357.) etc. is constructed equally has presented
Stretch and self-healing properties.In addition also have such as using electrostatic interaction (Nature Materials, 2013,12 (10),
932.) or the hydrogel of coordinate bond (Polymer Chemistry, 2013,4 (17), 4601.) interaction is also all shown
Good self-healing properties.These excellent achievements in research are the bases of the new high stretching selfreparing hydrogel of development, but this
The remediation efficiency of a little materials still remains limitation, it is necessary to prolonged repair time, how to keep the hydrogel to have excellent drawing
On the premise of stretching performance, the efficiency of the selfreparing of hydrogel is increased substantially, and simplify the process prepared there is important grind
Study carefully and application value.
The content of the invention：
The present invention is intended to provide a kind of stretch quick selfreparing physical hydrogel based on a kind of height of non-covalent bond effect preparation
Preparation method, this method prepare hydrogel overcome the strength problem of conventional hydrogels and be difficult to realize asking for selfreparing
Topic, preparation method is simple, simple, cheap and easy to get without special mechanical equipment and raw material.
A kind of preparation method of high quick selfreparing physical hydrogel of stretching provided by the present invention comprises the following steps：
Acrylic acid, Iron(III) chloride hexahydrate, water soluble starter, large hydrophilic molecular are made into pre-polymerization liquid, described pre-
Poly- liquid is placed in the mould of two pieces of glass plate compositions, and quick selfreparing thing is stretched by the way that Raolical polymerizable one-step synthesis is high
Manage hydrogel；The Raolical polymerizable condition is uv photopolymerization, and illumination power is 36W, when the reaction time is 12 small.
The water soluble starter is 2- hydroxyls -4'- (2- hydroxy ethoxies) -2- methyl phenyl ketones, 2- hydroxyls -4'- (2- hydroxyls
Ethyoxyl) -2- methyl phenyl ketones quality be acrylic acid quality 1wt%.
The concentration of acrylic acid is 2.0~4.0mol/L in the pre-polymerization liquid.The matter of the acrylic acid and large hydrophilic molecular
