Abstract

The invention relates to a method for growing nano-titanium oxide on the surface of glass fiber. In the method, the surface of chopped glass fiber is effectively modified by self-polymerization of dopamine on the surface of glass fiber, and then the surface of dopamine is modified by hydrothermal synthesis. Nano titanium oxide is grown on the surface of the glass fiber. The dopamine polymerization-modified glass fiber of the present invention has simple process, low cost and simple operation, and the prepared nano-titanium oxide is evenly distributed on the glass fiber, and its shape and size are adjustable and controllable, which is suitable for large-scale chopped glass fiber surface Nano-TiO growth.

Description

technical field [0001] The invention relates to a method for growing nano-titanium oxide on the surface of glass fibers, and belongs to the technical field of fiber modification and fiber synthesis. Background technique [0002] Nano-titanium oxide is an important nano-metal oxide, which has the characteristics of good chemical stability, high thermal stability, non-toxicity and non-migration, and has self-cleaning, antibacterial, anti-ultraviolet and other functions, and is widely used in photoelectric Catalytic catalyst, coating, food packaging, aerospace and other fields. In the field of building materials, nano-titanium oxide is also gradually integrated, which provides a new way to improve the performance of building materials and develop functional building materials: coating nano-titanium oxide on the exterior wall of the building realizes the surface of the exterior wall. Effective self-cleaning maintains the appearance cleanliness and aesthetics of the building; th...
