为解决VO_2热致变色薄膜可见光透射率低、耐候性差以及热分解法制备VO_2纳米颗粒易团聚等问题,提出了一种基于VO_2@SiO_2核壳纳米粒子的热致变色薄膜。首先利用VO(OH)_2表面负电荷和 γ-氨丙基三乙氧基硅烷中氨基正电荷间的静电相互作用,在前驱体VO(OH)_2表面进行SiO_2包覆得到VO(OH)_2@SiO_2核壳纳米粒子,然后在Ar气氛下对其进行高温热处理得到VO_2@SiO_2核壳纳米粒子,将其分散至树脂中并涂覆在玻璃基材上得到热致变色薄膜,并对热致变色薄膜的热致变色性能及核壳粒子的耐候性进行了研究。从透射电镜照片可以看出SiO_2壳层可以阻止前驱体VO(OH)_2在热分解过程中的团聚长大,对光学性能的研究表明低折射率的SiO_2和空气能够提高热致变色薄膜的光学性能,并且当VO(OH)_2@SiO_2纳米粒子的质量分数为10wt%时复合薄膜的光学性能最佳。SiO_2壳层对VO_2的保护作用可以有效提高其抗氧化性,并且可以提升纳米颗粒在酸性环境下的耐腐蚀性,延长热致变色薄膜的使用寿命。 |

A thermochromic film was prepared with VO_2@SiO_2 core-shell nanoparticles to enhance the visible light transmittance and weather resistance of thermochromic film and also decrease the agglomeration of VO_2 nanoparticles prepared by thermal decomposition method.VO(OH)_2@SiO_2 coreshell nanoparticles were prepared by coating SiO_2 layer on the surface of VO(OH)_2 nanoparticles via the surface electric interaction between nagatively charged VO(OH)_2 nanoparticles and positively charged NH2 groups of aminopropyltriethoxylsilane.Then a normal heat treatment of VO(OH)_2@SiO_2 under Ar atmosphere was utilized to obtain VO_2@SiO_2 nanoparticles.Subsequently optical film with good thermochromic property was prepared by coating the resin dispersion of VO_2@SiO_2 on well cleaned glass.The thermochromic property and the weather resistance of thermochromic film were studied.From TEM images,we find that SiO_2 shell prevents the agglomeration of VO(OH)_2 during heat treatment.Research on the optical properties of the film shows that the SiO_2 and air of low refractive index can improve the optical properties of thermochromic films,and when the mass fraction of VO_2@SiO_2 nanoparticles is 10wt%,the optical performance of the composite film is the best.The protective effect of the SiO_2 shell to the VO_2 core obviously improves the oxidation resistance and corrosion resistance of VO_2 in damp heating and acidic environment,which makes longer life of VO_2 thermochromic film. |
