Abstract
It is a good choice to mix hollow SiO2 nanoparticles with organic resins to prepare mechanically robust and flexible anti-reflective coating. In this paper, hollow SiO2 nanoparticles with adjustable size, good dispersion and homogeneity were prepared by polyacrylic acid template, in which the size of the hollow silica nanoparticles can be adjusted between 60 and 370 nm. Hollow SiO2 nanoparticles were compounded with UV-cured silsesquioxanes sol to prepare four sets of composite coatings with refractive indices of 1.11, 1.20, 1.27 and 1.36. Each of these coatings can result in a significant reduction in the reflectance of the PET substrate and can result in the lowest reflectance of the PET substrate to 1.63 %, 1.26 %, 0.96 % and 1.45 %, respectively. Among them, the coating with the lowest reflectance result can reduce the average reflectivity of the PET substrate in the 400–1000 nm band from 5.92 % to 2.02 %. In addition, the organic resins can connect the hollow SiO2 nanoparticles together to improve the mechanically robust of the coating. The results of the pencil hardness tester showed that the mechanical properties of the composite coating were significantly improved. The composite anti-reflective coating with hollow SiO2 nanoparticles and organic resin not only has excellent anti-reflective performance in flexible substrate materials, but also has great application prospects in photovoltaic glass, architectural glass and other fields.
期刊介绍：
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
