Abstract
The present invention relates to biomimetic material technology, it is substantially the single-layer or multi-layer composite material of internal particle orientations that specially a kind of biomimetic material by the adjusted and controlled preparation in outfield, the biomimetic material, which has shape memory characteristic,.Biomimetic material prepared by the present invention has good deformation effects, after environmental stimuli is withdrawn from, and can restore rapidly, and reset property is strong.
Description
[technical field]
The present invention relates to composite material and shape memory high molecule material field, in particular to outfield auxiliary prepares composite wood
Material technology, biomimetic material technology and shape memory material technology.
[technical background]
Shape-memory polymer (SMP) refers to that the product with original shape changes its primary condition under certain conditions
And after fixing, the macromolecule of its original shape can be restored again by the stimulation of external condition (such as heat, electricity, light, chemical co-ordination)
Material.The preparations such as common cross-linking method, copolymerization method, self-assembly method, are widely used in the fields such as medical treatment, military project, space flight.
It stepped into for 20th century, with bionic development and enriches, the type of shape-memory polymer has also enriched therewith
Come, large quantities of bionical shape-memory materials are come out one after another, such as the Chinese patent CN 109206620 of The Hong Kong Polytechnic University's application
A discloses a kind of bionical water-responsive shape memory polyaminoacid material and preparation method thereof.But it is current in actual production
The problems such as bionical generally existing cost input of memory material is high, and reset property is undesirable.Therefore, how low cost prepare it is high performance
Shape-memory material is the hot spot that each researcher falls over each other to probe into.
[summary of the invention]
[solving the problems, such as]
The purpose of the invention is to provide a kind of biomimetic features memory materials.
It is another object of the present invention to be to provide a kind of design preparation method of biomimetic features memory material.
It is another object of the present invention to be to provide a kind of method for preparing biomimetic features shape-memory material by outfield.
[technical solution]
For above-mentioned market trend and existing product problem, the present invention provides a kind of novel bionic planforms to remember material
Material and preparation method thereof, the biomimetic features shape-memory material production technology is easy, low in cost, reset with higher.
The present invention can be achieved through the following technical solutions:
(1) organism structure and its shape-memory properties contact: selecting bionical object, specify internal particle arrangement architecture
With contacting for shape-memory properties: the swelling of matrix in one direction can be limited in the particle that anisotropy arranges to reach solid
Setting becomes, and swelling can efficiently reset again when restoring.
(1) using liquid macroimolecule elastomer as matrix, curing agent and sound the design and preparation of biomimetic features: are added thereto
The particle in outfield is answered, is poured into the adjustable mold of thickness after mixing, covers die cover, is remembered according to organism structure and shape
The connection for recalling performance carries out outfield orientation process to mixed liquor.Meanwhile for multi-layer biological structure, after layer of material solidification,
Iteration scheme (2) carries out MULTILAYER COMPOSITE.
[beneficial effect]
Since present invention employs technical solutions as above, thus have the advantages that
1, deformation is rapid:, can be quick when the biomimetic features shape-memory material meets solvent or other environmental stimulis
Complete deformation；
2, restore rapid: the biomimetic features shape-memory material, can the original shape of fast quick-recovery when environmental stimuli is withdrawn from
Shape；
3, size is customized: being directed to different suitable environments, the biomimetic features shape-memory material can freely cut into institute
The shape and size needed；
4, reset property is strong: the biomimetic features shape-memory material deformation recovery rate has up to 98% or more in actual test
Good deformation recovery effects；
5, processing preparation is simple: the mold for filling mixed liquor being placed in outfield, is remembered according to organism structure and its shape
Recall the connection of performance, changes differently- oriented directivity to controlled material structure, can be obtained the bionical memory material.
[Detailed description of the invention]
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention do into
The detailed description of one step, in which:
Fig. 1 is pine nut scale internal microstructure schematic diagram；
Fig. 2 is flow chart --- the system of pine nut biomimetic features shape-memory material designed according to the present invention with preparating example
It is standby.
Fig. 3 is the double membrane structure schematic diagram of pine nut biomimetic features shape-memory material.
Fig. 4 is that the deformation of pine nut biomimetic features shape-memory material and deformation restore comparison diagram.
[specific embodiment]
Hereinafter reference will be made to the drawings, and a preferred embodiment of the present invention will be described in detail.It should be appreciated that preferred embodiment
Only for illustrating the present invention, rather than limiting the scope of protection of the present invention.
In Fig. 1,1- pine nut scale tissue, rod-shaped particle at 2- pine nut scale.
In Fig. 3,1- section "-" orientation texture composite film, 2- section " I " orientation texture composite film, the rodlike filler of 3-
Particle.
A kind of embodiment 1: specific example of the invention: pine nut biomimetic features shape-memory material.With polydimethylsiloxanes
Alkane (PDMS) is used as flowable media, and short fibre nickel-coated carbon fibers (NiCF) are as orientation particle, by NiCF and PDMS with mass ratio
It is mixed and made into mixed liquor for the ratio of 1:10, and curing agent is added into mixed liquor, and curing agent and PDMS mass ratio are 1:10.
By gained liquid after homogenizer vacuum homogeneous, uniformly pours into mold 1, cover die cover.Die horizontal moves into vertical magnetic field,
Mold is integrally warming up to 100 DEG C, constant temperature 90min by temperature control device, single layer can be obtained and imitate pine nut scale material.It again will be single
Layer material is placed in mold 2, fills mixed liquor, mold is integrally perpendicularly fixed in magnetic field, is heating and curing and pine nut can be obtained
Biomimetic features shape-memory material.
