Abstract

With the rapid development of nanotechnology, its application in the modification of chemical engineering materials is becoming more and more extensive, which provides new possibilities for the performance improvement of traditional materials and the development of new functional materials. This paper discusses the application basis of nanotechnology in material modification, including the surface effect of nanoparticles, the quantum effect of nanostructures and the formation mechanism of nanocomposites. These application bases provide theoretical support for the subsequent material modification. In Chapter 4, the application of nanotechnology in different chemical engineering materials is analyzed in detail, including polymer matrix composites, me tal matrix composites, ceramic matrix composites and functional materials. Examples show how nanotechnology can significantly improve mechanical properties, thermal stability, fracture toughness, and applications in sensors and catalytic materials. Chapter 5 focuses on the improvement of properties of nano-modified materials, including mechanical properties, thermal and electrical properties, optical and magnetic properties, and environmental stability of materials. These improvements open up new avenues for industrial applications of the material.
