Although polyethylene (PE) is one of the most frequently used synthetic polymers in the plastics market, it is very difficult to imprint or bond PE with adhesives without pre-treatments based upon electrical, chemical and thermal processes. This is because a uniform adhesion property of PE cannot be expected without these processes. In this study, we suggest a simple, fast and cost-effective method to improve the adhesion properties of PE using a Kapton tape, which is a polyimide film generally used in flexible electronics. Specifically, by wrapping PE substrates applied with an adhesive using a Kapton tape and curing the sample using either a hot-press or a hot plate, the standard deviation of the shear strength decreased by 82.1% and 87.6%, respectively. To further improve the adhesion of PE substrates, we functionalized their surface using coupling agents, such as (3-glycidoxypropyl) methyldiethoxysilane and (3-aminopropyl) trimethoxysilane after an ultraviolet-ozone process. Using X-ray photoelectron spectroscopy and vacuum Fourier-transform infrared spectroscopy analysis, we proved that a significant improvement in the adhesion of PE occurred because of chemical crosslinking between either epoxy or amine groups functionalized on the PE substrates and epoxy-based adhesives comprising diglycidyl ether epoxy resin and triethylenetetramine hardener. This study is important, as it suggests a simple and very effective method to obtain highly reliable adhesion properties of PE using conventional adhesives.

一种使用 Kapton-taping 工艺增强聚乙烯粘合性能的简单且高度可靠的方法

尽管聚乙烯 (PE) 是塑料市场上最常用的合成聚合物之一,但如果没有基于电气、化学和热工艺的预处理,则很难用粘合剂压印或粘合 PE。这是因为如果没有这些过程,就无法期望 PE 具有均匀的粘合性能。在这项研究中,我们提出了一种简单、快速且具有成本效益的方法来使用 Kapton 胶带提高 PE 的粘合性能,Kapton 胶带是一种通常用于柔性电子产品的聚酰亚胺薄膜。具体而言,通过使用 Kapton 胶带包裹涂有粘合剂的 PE 基材并使用热压机或热板固化样品,剪切强度的标准偏差分别降低了 82.1% 和 87.6%。为了进一步提高PE基材的附着力,我们使用偶联剂对其表面进行功能化,例如(3-缩水甘油氧基丙基)甲基二乙氧基硅烷和(3-氨基丙基)三甲氧基硅烷,经过紫外线-臭氧处理后。使用 X 射线光电子能谱和真空傅里叶变换红外光谱分析,我们证明 PE 的粘合性显着提高,因为在 PE 基材上官能化的环氧基或胺基与包含二缩水甘油醚的环氧基粘合剂之间发生化学交联环氧树脂和三亚乙基四胺硬化剂。这项研究很重要,因为它提出了一种简单且非常有效的方法,可以使用传统粘合剂获得高度可靠的 PE 粘合性能。使用 X 射线光电子能谱和真空傅里叶变换红外光谱分析,我们证明 PE 的粘合性显着提高,因为在 PE 基材上官能化的环氧基或胺基与包含二缩水甘油醚的环氧基粘合剂之间发生化学交联环氧树脂和三亚乙基四胺硬化剂。这项研究很重要,因为它提出了一种简单且非常有效的方法,可以使用传统粘合剂获得高度可靠的 PE 粘合性能。使用 X 射线光电子能谱和真空傅里叶变换红外光谱分析,我们证明 PE 的粘合性显着提高,因为在 PE 基材上官能化的环氧基或胺基与包含二缩水甘油醚的环氧基粘合剂之间发生化学交联环氧树脂和三亚乙基四胺硬化剂。这项研究很重要,因为它提出了一种简单且非常有效的方法,可以使用传统粘合剂获得高度可靠的 PE 粘合性能。我们证明 PE 的粘合性显着提高,这是因为在 PE 基材上官能化的环氧基或胺基与包含二缩水甘油醚环氧树脂和三亚乙基四胺硬化剂的环氧基粘合剂之间发生化学交联。这项研究很重要,因为它提出了一种简单且非常有效的方法,可以使用传统粘合剂获得高度可靠的 PE 粘合性能。我们证明 PE 的粘合性显着提高,这是因为在 PE 基材上官能化的环氧基或胺基与包含二缩水甘油醚环氧树脂和三亚乙基四胺硬化剂的环氧基粘合剂之间发生化学交联。这项研究很重要,因为它提出了一种简单且非常有效的方法,可以使用传统粘合剂获得高度可靠的 PE 粘合性能。
