We are delighted to present this special-themed issue of the Chinese Journal of Polymer Science (CJPS) devoted to the recent advances in self-healing polymeric materials.Self-healing has been recognized as one of the most attractive topics for advanced polymers in the past few years,enabling their reworkability,durability and reliability.Since the emergence of the concept,self-healing polymeric materials have been rapidly evolving and have revolutionized many aspects of polymer sciences.Nowadays,this type of smart materials has found broad prospects for both structural and functional applications including space vehicles,aircrafts,artificial skins,soft robots,energy devices,coatings,and sensors.This special issue consists of 3 feature articles,2 review articles,and 6 regular articles,focusing on the latest research achievements in dynamic networks,self-healing elastomers,supramolecular polymers,hybrid polymers,and so on.

针对目前超高桥墩垂直度检测方法存在危险系数较高、精度难以保证或自动化程度与工作效率较低的情况,本文提出一种基于三维激光扫描技术的点云数据超高桥墩位姿自动检测方法。该方法首先将海量墩面点云双向分层;然后依条件选择分层文件探测点云投影线并划分桥墩面缓冲区;最后根据缓冲区自动提取墩面点云并进行位姿检测。本文以某山区高速桥梁高墩位姿检测为例进行试验,试验结果,表明该方法具有无接触测量、高自动化、高工作效率
Owing to the advantages of non-volatility,outstanding fluidity and easy recyclability,ionic liquid-based electronics,such as thermometer,strain sensors and thermoelectric converters,have been growing as attractive alternatives to traditionally solid elect
利用高分辨率立体测绘卫星遥感影像进行地貌更新,因其覆盖面积大、更新周期短等优势,在中小比例尺地貌要素更新中具有极大的应用潜力。本文分别利用WorldView-2和资源三号卫星影像,探索基于高分辨率立体测绘卫星影像的中小比例尺地貌更新技术方案流程,并在不同的试验区开展试验验证。试验结果表明:本文方法能够满足1∶50 000比例尺地形图地貌更新精度要求,更新效率提升了约25%。
Photoinduced reversible liquefaction and solidification of polymers enable processing and healing of polymers with light.Some azobenzene-containing polymers (azopolymers) exhibit two types of photoinduced liquefaction properties:photoinduced reversible so
