Description
Technical field
This utility model relates to low temperature procedure controlledly synthesis equipment technical field, especially relates to the porous regular hydrogel complexes that a kind of new type low temperature program is controlled, orientation is freezing, rate controlling synthesizes.
Background technology
Hydrogel is the three-dimensional network between liquid and solid or interpenetrating networks, is that one can swell in water significantly, but the hydrophilic polymer gel that can not dissolve in water, although hydrogel is containing large quantity of moisture, certain shape can be demonstrated as solid.Particularly environmental sensitive hydrogels, is one of emphasis and the forward position of polymer science area research.
But, the problem that ordinary construction hydrogel performance exists two aspects: one be the water suction of starting stage be a kind of physical process, act on more weak, slowly, thus the rate of water absorption of starting stage is the lowest for the diffusion velocity of hydrone；Two is owing to the randomness distribution in system of the crosslinking points of Common hydrogels causes its chain link different in size, the stress that every chain be can bear is different, first shorter chain link ruptures, then rupturing of whole aquogel system is caused, bad mechanical property that therefore hydrogel is overall and the shortcoming such as swelling rear recoverability is bad.
Porous aquagel can reduce the osmotic resistance of water by capillarity, greatly increases the collaborative diffusion coefficient D value of hydrogel, it is thus possible to make gel be rapidly completed expansion or shrinkage after perceptible stimulus；Simultaneously, cavernous structure in hydrogel considerably increases the specific surface area within gel, more hydrophilic group can promptly be contacted with hydrone, and the water in hydrogel can be discharged through surface compact layer by hole, and the speed of response of hydrogel substantially increases.Regular micro structure hydrogel, for the weakness of Common hydrogels, is effectively had complementary advantages, Synergistic so that the combination property of hydrogel tends to perfect.
