Abstract

This invention relates to a process of preparing capsule-like nanometer grade material. First prepare a kind of compound nanometer formwork; then use this formwork to pack material. The compound formwork is formed by the way of CVDP which is depositing PPX or derivate on the inner wall of AAO. And it is a porosity and hollow AAO/PPX formwork. Fill it by other material and seal the extremity, drop the AAO. This material can be used for catalyst transporting, drug releasing, coaxial cable and so on.

Description

technical field [0001] The invention belongs to the technical field of nanometer and macromolecular materials, and in particular relates to a nanoscale material preparation method. Background technique [0002] One-dimensional nanomaterials are a research hotspot in recent years. The template method is an effective technique for synthesizing one-dimensional nanomaterials such as nanowires and nanotubes, which has good controllability. The template method usually uses a porous material with a pore size of nanometer to micrometer as a template, combined with electrochemical, precipitation, sol-gel method (C.R.Martin, Science, 1994, 266 (23): 1961) and vapor deposition method ( K.Kim, J.Jin, Nano Letters, 2001, 1 (11): 631) and other technologies allow material atoms or ions to precipitate on the pore walls of the template to form the desired nanostructure. However, some of these methods use solvents and add additives, initiators, etc., which have certain toxicity and the proc...
