Problems solved by technology

[0006] However, the melting point of polyethylene is higher than 110°C, the softening temperature of polysulfone ether is higher than 200°C, and it cannot be shaped or deformed at 50-60°C
Considering safety issues, medical devices and medical supplies used for hot compress therapy need to be heated by a DC power supply below 36V. In order to achieve good application and improve the effect of hot compress therapy, it is hoped that functional materials that can be molded at a temperature of 50-60°C have not yet been developed. reported

Abstract

The invention discloses a PCL conductive shapable material, and a preparation method and an application thereof, and belongs to the field of functional polymer materials. The PCL conductive shapable material is composed of the following substances by the mass percentage: 49%-98.4% of PCL, 1%-30% of a plasticizer, 0.5%-20% of carbon nanotubes, and 0.1%-1% of an antioxidant. After the components are mixed, the PCL conductive shapable material is obtained by melting the mixture with a twin-screw or single-screw extruder or an internal mixer. The PCL is modified by the carbon nanotubes, and with addition of N-N-butyl sulfonamide, the PCL is plasticized and the carbon nanotubes are subjected to surface treatment, so good dispersion of the carbon nanotubes is achieved while the softening temperature of the composite material is reduced, and good conductivity and shapable effect are obtained. The prepared conductive shapable functional material has the advantages of small volume resistance, low softening temperature and the like, and has good application prospects in the fields of hot compress medical apparatus and instruments, medical insulation pads, electric blankets and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PCL conductive and plastic material and a preparation method thereof, in particular to a carbon nanotube modified, N-butylbenzenesulfonamide plasticized PCL conductive and plastic functional material and its preparation method. The material has the characteristics of low electrical resistance and shapeability at low temperature. Background technique [0002] Carbon nanotubes were discovered in 1991. As a new type of one-dimensional nanomaterial, carbon nanotubes have many advantages such as light weight, excellent mechanical, electrical and chemical properties, and have become one of the research hotspots in the field of material science. In recent years, with the localization of carbon nanotubes and the reduction of their cost, the research on the performance of carbon nanotubes has been gradually deepened, and its application has been continuously expanded.
