Abstract

The invention relates to a preparation method of a phosphate silane-carbon nanotube composite film on the surface of a quartz substrate, belonging to the technical field of nanometer composite films. The method comprises the following steps: pretreating the quartz substrate through hydroxylation treatment; soaking carbon nanotubes in rare earth modifier at the room temperature for 2-6 hours, filtering, drying; placing 0.05-0.15mg/ml of the obtained carbon nanotubes in N,N-dimethylformamide dispersant, performing ultrasonic dispersion for 2-6 hours to obtain stable suspension; soaking the film substrate assembled with phosphate groups on the surface in the prepared carbon nanotube suspension, standing at 20-60 DEG C for 4-16 hours, taking out the phosphate to wash with a lot of deionized water, and drying with nitrogen after washing to obtain the quartz substrate with the modified carbon nanotube composite film on the surface. The process method in the invention is simple and the carbon nanotube composite film prepared on the surface of the quartz substrate has good optical properties.

Description

technical field [0001] The invention relates to a preparation method in the technical field of nanocomposite films, in particular to a preparation method for a phosphate-based silane carbon nanotube composite film on the surface of a quartz substrate. Background technique [0002] In recent years, with the rapid development of optical communication and integrated optics research, thin-film optical waveguides have been widely used in optical passive devices and integrated optical circuits. They can be used to complete many optical functions such as switching, modulation, and multiplexing. The reason is that optical Waveguide is not only the carrier for the rapid transmission of a large number of optical signals, but also the substrate of integrated optics in micro-optical circuits, such as optical phase modulators, optical intensity modulators, optical switches, waveguide-type optical couplers, wavelength division multiplexers, polarization splitters, etc. Beamers, optical fi...
