Description
Technical field
The present invention relates to functional high polymer material field, is answered more particularly to a kind of luminescence generated by light PDMS of ultraviolet light barrier
Condensation material and preparation method thereof.
Background technology
With the increase of industrial waste gas and tail gas discharge capacity, ozone layer is increasingly thin, particularly summer, the aerial floating layer in day or mist
Haze quantitative change is few, has more ultraviolets to reach earth surface in sunshine, directly to injure to mankind's skin tape and exactly tans severely, burns
Wound, even causes skin disease such as：Cutaneum carcinoma etc..Therefore, protect human skin from uv damage, Development of Novel ultraviolet
The material of barrier, it is significant to promoting the well-being of mankind.In the presence of ultraviolet, polymer is also easy to produce free radical, causes light
Degraded, accelerates the aging, discoloration and degraded of polymer coating, greatly reduces the service life of coating.Therefore, stable performance is developed
New ultra-violet protective materials be one of important focus of material science research.
Conventional ultraviolet blocking material is mainly made up of ultraviolet absorber and high score material；This be mainly reflected in coating,
The fields such as cosmetics, anti-counterfeiting mark.In general, ultra-violet absorber can be divided into two major classes, and one kind is organic uv absorbers,
Mainly include Benzophenone class, benzotriazole, bigcatkin willow vinegar class, oxanilide class etc.；Organic uv absorbers have ultraviolet suction
Backscatter extinction logarithmic ratio is big, shield effectiveness is high, shielding wide waveband, the transparency it is good the advantages that；But it is poor, volatile etc. light, heat endurance to be present
Shortcoming, also, organic uv absorbers catabolite has certain toxicity (CN 103436111A).Another kind of is with broad-band gap
Metal oxide semiconductor material, conventional mainly has TiO2、ZnO、CeO2And ZrO2Deng inorganic nano-particle.Although TiO2
There is good uv-shielding capacity with ZnO, but TiO2There is very high photocatalytic activity again simultaneously with ZnO, so that can be right
Surrounding medium and application base material carry out light degradation, particularly nano-ZnO, and aquatic organism can be killed by flowing in the waters such as rivers, make it
(Environmental Science＆Technology.2012 are extremely limited in actual applications；46:8181-
8188.)。CeO2Also there is stronger oxidation catalytic activity.Recently, there is Chinese patent (A of CN 101857713) report from multiple
Antioxidant (Hinered phenols and phosphorous acid esters are compound) is closed, weakens CeO2Oxidation catalytic activity, and suppress polyester by light-initiated
Free-radical oxidation reaction progress, realize that this composite both has good uv-shielding capacity, urge again with low light
Change and oxidation catalytic activity, light and oxidative degradation will not be carried out to surrounding medium and application base material.Although idea can use, make
It can not really suppress its oxidation activity with composite antioxidant, photodegradative problem be present, shorten the composite service life.Always
It, although inorganic nano-particle, with prominent uv-shielding capacity, under effect of sunlight, inorganic nano-particle also has
Very strong photocatalytic activity and oxidation activity, degradable polymeric matrix, shorten the service life of functional composite material
(Carbohydr.Polym.,2012,88(3):992-1001.)。
In recent years, si-nanocrystals are as important one kind " green " nano semiconductor material, due to its abundance, life
Thing compatibility is good, adjusts its particle size, thus it is possible to vary the launch wavelength and intensity of luminescence generated by light, is widely used in photoelectron device
The fields such as part, medical imaging and diagnosis.Compared with organic uv absorbers, si-nanocrystals toxicity is low, abundance, optical
Matter is unique, as ultraviolet absorber of new generation, has very wide application prospect.
