Abstract

The invention discloses a multi-layer self-driven tubular micro-nano motor constructed of kapok fiber / manganese dioxide and a preparation method thereof. Potassium permanganate is used as a raw material, kapok fiber is used as a template, and kapok fiber is soaked in permanganate In the potassium solution, the potassium permanganate and the kapok fiber undergo a redox reaction to generate manganese dioxide nanoparticles loaded on the kapok fiber, thereby preparing a multilayer self-driven tubular micro-nano motor with good biodegradability. At the same time, it has the functions of carrying, transporting and releasing, and has broad application prospects in the fields of efficient drug loading, targeted cancer cell transport, near-infrared photoresponsive controllable release of drugs, and environmental governance.

Description

technical field [0001] The invention belongs to the technical field of micro-nano motors, and in particular relates to a multi-layer self-driven tubular micro-nano motor constructed of kapok fiber / manganese dioxide and a preparation method thereof. Background technique [0002] At present, the preparation of micro-nano motors has become one of the hottest directions in nanotechnology research. A micro-nano motor is a nano- or micron-level device that can move and convert different forms of energy such as electrical energy, magnetic energy, light energy, and chemical energy into driving force and its own kinetic energy. There are many types of micro-nano motors, and the preparation methods of different shapes of micro-nano motors are also different, for example: linear micro-nano motors are usually prepared by template-assisted electrodeposition; Janus spherical micro-nano motors are usually prepared by microsphere template method; Motors are typically prepared using crimpin...
