Physical motion forms and properties of biopolymers based on nanotubes

Abstract

In order to prepare nanotube-modified biomaterials from a certain amount of unmodified multiwalled carbon nanotubes (MWCNTs), the physical movement and properties of biopolymers based on nanotubes were studied. The tribophysical movement of biopolymers based on nanotubes was simulated by using the corresponding instruments and software packages. The experimental potential and tight-binding potential of the NON7 software package were used to simulate the physical movement of biopolymers based on nanotubes. X-ray diffraction, scanning electron microscopy and a DMA 242 C instrument were used to study the thermal transformation and perform dynamic mechanical thermal analysis of the modified biopolymers. The results show that the biopolymer based on MWCNTs vibrates only slightly in the process of molecular adhesion, and its structural characteristics have no obvious deformation. The biopolymers based on MWCNTs have good lubricity, while the crystallinity of the biopolymers based on MWCNTs is positively correlated with temperature. When the optimum ratio is exceeded, there is a significant negative correlation between the tensile strength and the number of nanotubes.
