| 摘 要： | 为改善大理石在酸雨和酸雾环境下的耐蚀性能，运用仿生合成方法在大理石表面制备了一层壳聚：糖／二氧化硅（CS／SiO2）保护膜。通过扫描电子显微镜和红外光谱对膜的形貌结构进行了表征，并对膜的基本性质进行了测试。结果表明：CS／SiO2膜以球形颗粒沉积在大理石表面，保持了其原有的透气性，减小了其吸水性；膜的耐酸性能优越，显著...

| Abstract: | Chitosan/silica protective coating was prepared on the surface of marble by making use of biomime-tic synthetic method.The morphology and chemical feature of as-prepared protective coating were analyzed by means of scanning electron microscopy and Fourier transform infrared spectrometry,and the performance of the coating was evaluated as well.Results show that as-prepared chitosan/silica protective coating on the surface of marble is composed of spheric particles,and it is able to retain air permeability and decrease the water-absorption capacity.As-prepared chitosan/silica protective coating had good resistance against acid attack and thereby was able to significantly increase the corrosion resistance of marble.As-prepared chitosan/silica protective coating possessed good adhesion to marble substrate as well as good resistance against freeze-thaw and heat deterioration. |
