Description
Technical field
The present invention relates to a kind ofly can regulate intelligent light modulation film of transparence and preparation method thereof automatically, can be applied to the transparent roofs and the solar energy heat collector of forms, greenhouse brooder or some building venue of the buildings or the vehicles according to variation of ambient temperature.
Background technology
Effective daylighting of the interior space such as the buildings and the vehicles and solar energy heat collector is one of key element of human society daily life and development green low-carbon economy.In recent years, along with the raising of countries in the world to green energy resource and low-carbon economy attention degree, the effective utilization of sun power and the exploitation of energy-conserving and environment-protective material have received people's extensive concern.For the buildings and the vehicles, reasonably unnecessary power consumption (illumination and heating) can be effectively avoided in the design of indoor lighting and form layout; But the spinoff that produces is too much the injecting and can cause room temp too high of sunshine in summer, needs air conditioner refrigerating to lower the temperature, and this has increased power consumption undoubtedly again.For solar energy heat collector, do not need too high temperature sometimes yet.In recent years, software engineering researchers invent " smart window (Smart Window) ", the intelligent dimming coated materials on window glass, or is loaded among the window glass interlayer.The intelligent dimming material can be regulated transparence automatically according to indoor environment, with injecting of regulation and control sunlight.For example, during winter, window keeps vitreous state, and injecting of sunlight can be warmed oneself for the room; In summer, when room temp was higher than a certain value, window transparency reduces to reduce sunlight to be injected, thereby has avoided room temp overheated.
The optics regulating switch of smart window material can induce the oxidation-reduction of liquid crystal orientations, suspended particle dispersion or chromophore to change through electric field action, to realize transparent-muddy transformation of smart window; Photochromic material also is applied to smart window, mainly is to change through the light transmission that uv-radiation causes; Another kind of important smart window material is a thermochromic material, utilizes the variation of envrionment temperature to regulate transparence, comprises that inorganics is like silver, mercury, cadmium, titanium, vanadium compound and polymer-based material.Because its low cost and ease for operation, the temperature sensing polymer hydrogel demonstrates wide application prospect in the smart window field.Its principle is when temperature is higher than a certain critical temperature, and the avidity of polymkeric substance and water sharply descends and is separated, the macroscopic appearance that shows be system by the transformation of clear state to muddy attitude, thereby cause the reduction of transparence.The temperature sensitive type water-soluble polymers comprises hydroxypropylcellulose (HPC), Vltra tears (HPMC), gather (N-NSC 11448) (PNIPA), gather (methylvinylether) (PVME), gather (N; The N-ethyl acrylamide) (PDEAM), gather (N-caprolactam) (PVCL) with gather (2-sec.-propyl-2-oxazoline) (PIPO), polyoxyethylene-polyoxytrimethylene-polyoxyethylene triblock copolymer (PEO-PPO-PEO; Pluronic), these polymkeric substance demonstrate huge application potential in the intelligent material field.Reported temperature sensitive type water-soluble polymer solution or gel based smart window comprise: HPC or HPMC be as main material, adds additive and be mixed with the aqueous solution or gelinite (Sol.Energ.Mat.Sol.Cells 1998,54:203-211; Door and window 2009,4:42-44; CN1621458A; CN1986630A), PVME based sols or gel (New Building Materials 2007,34:32-34; US5404245), PNIPA base gel (Polym.Adv.Technol.2003,14:757 – 762) places glass sandwich or makes film forming.An important feature of temperature sensitive polymer is on critical temperature LCST, can be separated, and changes muddy attitude into by clear state, may generate deposition sometimes; If but made the body gel, its disadvantage would be to be accompanied by transparency change also tangible volumetric shrinkage can take place.When being applied to smart window, liquid system can't film forming, can only be used as the interlayer packing material, is prone to take place layering and flocculation in the life-time service process; The solid gel system can effectively be avoided the generation of the problems referred to above, removes as sandwich material and also can use with mould material separately, but must guarantee that gel-film itself volume does not take place changes with epidermis wrinkling mutually.Therefore, can consider the temperature sensitive polymer uniform dissolution can not taken place in the aquogel system of phase-splitting in other.Document [New Building Materials 2007,34:32-34] and patent (CN101608021B) in cross-linking polyvinyl alcohol (PVA) based aquagel system, have obtained to have certain elasticity and flexible intelligent light modulation film with PVME or NIPA based polyalcohol IPN.Patent CN1986630A then is on the basic components of existing patent (CN1621458A) technology, has added a kind of gelifying agent such as XG 550, carrageenin or gelling gum again, has obtained the solid film under the normal temperature.Document [Smart Mater Struct.2011; 20:075005] then polyoxyethylene-polyoxytrimethylene-polyoxyethylene/polyoxyethylene octylphenol ether (PEO-PPO-PEO/TX-100) mixed system of temperature sensitive property is aided with other additive and is embedded in sepharose, prepared intelligent light modulation film.Though the above-mentioned solid water gel of having reported as the temperature sensitive polymer carrier has overcome the inherent shortcoming of liquid polymer solution own; But also come with some shortcomings: although can give snappiness and toughness like the PVA system, the author has confirmed that the PVA macromole particularly is easy to crystallization winter and separates out and cause the irreversible muddiness of film under low temperature environment; Though XG 550, carrageenin or gelling gum can be with temperature sensitive polymer solution solid states, it is only undertaken crosslinked by physical action, and its mechanical property is difficult to reach the requirement of using separately as film; Though agarose aquogel has certain intensity; But need be under hot environment that all film forming raw materials mix are even in the preparation process; Change over to and cool off film forming in the mould,, need to adopt ultrasonic concussion to guarantee its homodisperse because temperature sensitive polymer is assembled under the high temperature; And entire operation needs under the high temperature to accomplish, and this has increased the loaded down with trivial details property of energy consumption and operation undoubtedly.
Summary of the invention
