Abstract

Cold atmospheric plasma (CAP) finds numerous applications across various sectors, including industry (e.g. surface modification) and medicine (e.g. tissue regeneration, wound healing, oncology, and dentistry). However, understanding the mechanical properties of materials undergoing CAP treatment is of great importance, particularly for applications involving changes in material properties. This study aims to utilize CAP as an excitation device for assessing the mechanical properties of a polymethyl methacrylate (PMMA) sample. CAP was employed to induce vibrations on a PMMA sample around its resonance frequency, and the resulting vibrations were measured by a scanning laser doppler vibrometer. The elastic modulus of the PMMA sample was then calculated based on the stress and strain profiles obtained from the measured vibrations. The obtained elastic modulus value of 4.87 GPa showed excellent agreement with the 4.83 GPa value obtained using other excitation devices, indicating the reliability of CAP in mechanical characterization. This study is the first step toward potential applications that can break new ground in the use of CAP in monitoring and characterization of mechanical properties during CAP treatment (e.g. surface treatment), paving the way for enhanced control and optimization of CAP-based processes in various applications.

用冷大气等离子体激发和激光振动仪表征材料

冷大气等离子体（CAP）在各个领域都有广泛的应用，包括工业（如表面改性）和医学（如组织再生、伤口愈合、肿瘤学和牙科）。然而，了解经过CAP处理的材料的机械性能是非常重要的，特别是对于涉及材料性能变化的应用。本研究旨在利用CAP作为激励装置来评估聚甲基丙烯酸甲酯（PMMA）样品的力学性能。利用CAP在PMMA样品上诱导其共振频率附近的振动，并通过扫描激光多普勒振动计测量产生的振动。然后根据测量振动得到的应力和应变曲线计算PMMA样品的弹性模量。得到的弹性模量值为4.87 GPa，与使用其他激励装置得到的弹性模量值4.83 GPa有很好的一致性，表明CAP在力学表征中的可靠性。这项研究是迈向潜在应用的第一步，可以在CAP处理（例如表面处理）期间使用CAP监测和表征机械性能方面开辟新的领域，为各种应用中基于CAP的过程的加强控制和优化铺平道路。图形抽象

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
