An In-Depth Analysis of the Scientific Connotations,Testing Methods,and Applications of Free Volume in Polymer Physics
摘要
Abstract
The concept of free volume originated from the study of liquid viscosity and was later utilized by Fox and Flory in the analysis of the glass transition in polymer materials,establishing itself as a crucial tool for understanding various physical phenomena in polymers.However,there is currently a lack of comprehensive discussion on free volume in educational contexts.This paper provides an overview of the origin,definition,and applications of free volume,explores different testing methods,and investigates the relationship between free volume and the physical properties of polymers.The study aims to deepen students'understanding of the free volume concept,promote a comprehensive grasp of polymer physical processes,and inspire interest and enthusiasm for scientific research.关键词
