Abstract

Since the invention of atomic force microscopy (AFM), researchers have been able to study the statistical mechanical properties of individual polymer chains by using a technique known as single molecule force spectroscopy (SMFS), which stretches a single polymer chain by attaching one end of the chain to a substrate and the other end to the AFM tip. SMFS is used to obtain static information about single polymer chains, mainly through a quasistatic stretching process. With technological developments in recent years, dynamic SMFS measurements under nonequilibrium conditions have also been realized. The dynamic viscoelasticity of single molecule chains can also be measured, which will benefit our understanding of the nonequilibrium dynamic properties of polymeric materials.

聚合物单链的静态和动态力学性能

自从原子力显微镜（AFM）发明以来，研究人员已经能够通过使用一种称为单分子力谱（SMFS）的技术来研究单个聚合物链的统计力学性能，该技术通过将链的一端连接到基底，另一端连接到AFM尖端来拉伸单个聚合物链。SMFS主要通过准静态拉伸过程来获得聚合物单链的静态信息。随着近年来技术的发展，也实现了非平衡条件下的动态SMFS测量。还可以测量单分子链的动态粘弹性，这将有助于我们理解聚合物材料的非平衡动力学性质。

期刊介绍： For the communication among the members, the journal of the Society of Rheology Japan, NIHON REOROJI GAKKAISHI (5 issues per year), was established in 1973 and it is the oldest journal on rheology in Asia. The journal contains original and review articles on rheology and related topics, information for all SRJ events, and reports of domestic/overseas meetings. Articles in Japanese as well as in English are considered for publication, not only from the members but also from the researchers outside. Papers from new emerging areas of the field are particularly welcome. The electronic version of the articles is available via the internet with an open access policy.
