Abstract

Relevant experiments are essential to clearly understand the role of various molecular (chemical structure, surface energy, composition), experimental (contact time, contact pressure, temperature) or topological (sample roughness and thickness) parameters, on the tack properties of pressure sensitive adhesives (PSA). The “mechano-optical tack tester” (MOTT) is a novel device that we have developed to provide accurate measurements of both the contact area and the tack strength. The MOTT is designed to apply controlled contact pressures by mean of a quartz prism probe, for determined contact times, onto the surface of PSA samples. The probe is then pulled up at controlled rates while the tearing force (tack strength) and the contact area are plotted versus time. The tack energy is then calculated. Using the MOTT, the influence of various parameters (contact pressure, contact area, sample thickness, …) on the tack properties of PSA samples has been studied. The main result lies in the strong dependence of the tack energy on the sample thickness. This points out that the release energy is close to the interface rather than in the bulk of the PSA films, and is a function of the contact area. © 2000 John Wiley & Sons, Inc.

压敏胶粘剂的粘性特性

相关实验对于清楚地了解各种分子(化学结构、表面能、组成)、实验(接触时间、接触压力、温度)或拓扑(样品粗糙度和厚度)参数对压敏胶粘剂(PSA)粘接性能的作用至关重要。“机械光学粘性测试仪”(MOTT)是我们开发的一种新型设备，可以提供接触面积和粘性强度的精确测量。MOTT设计用于通过石英棱镜探头控制接触压力，确定接触时间，到PSA样品表面。然后以控制的速率将探针拉起，同时绘制撕裂力(粘性强度)和接触面积随时间的变化。然后计算出粘性能。利用MOTT技术，研究了不同参数(接触压力、接触面积、试样厚度等)对PSA试样粘接性能的影响。主要结果在于黏着能对试样厚度有很强的依赖性。这表明释放能量靠近界面而不是在PSA膜的主体中，并且是接触面积的函数。©2000 John Wiley & Sons, Inc[J]生物质化学工程学报，2009,31 (2):391 - 398

期刊介绍： Since its launch in 1946 by P. M. Doty, H. Mark, and C.C. Price, the Journal of Polymer Science has provided a continuous forum for the dissemination of thoroughly peer-reviewed, fundamental, international research into the preparation and properties of macromolecules. From January 2020, the Journal of Polymer Science, Part A: Polymer Chemistry and Journal of Polymer Science, Part B: Polymer Physics will be published as one journal, the Journal of Polymer Science. The merged journal will reflect the nature of today''s polymer science research, with physics and chemistry of polymer systems at the heart of the scope. You can continue looking forward to an exciting mix of comprehensive reviews, visionary insights, high-impact communications, and full papers that represent the rapid multidisciplinary developments in polymer science. Our editorial team consists of a mix of well-known academic editors and full-time professional editors who ensure fast, professional peer review of your contribution. After publication, our team will work to ensure that your paper receives the recognition it deserves by your peers and the broader scientific community.
