Polymer molecular behaviors at buried polymer/metal and polymer/polymer interfaces and their relations to adhesion in packaging

Surface Structure of Acrylate Polymer Adhesives

“…SFG is therefore established as a sensitive probe of polymer surface structure. [11][12][13][14][15][16][17][18][19][20][21][22][23][24] However, it is often challenging to separate the effects of orientation from changes in concentration in the SFG signal. In this study we will therefore combine IR absorption and SFG spectroscopy to study the drying process of butyl acrylate PSAs containing varying amounts of acrylic acid.…”

Studying Polymer Surfaces and Interfaces with Sum Frequency Generation Vibrational Spectroscopy

“…We have briefly summarized our SFG studies on polymer/metal interfaces in a recent review. 151 Here, we will include more details and present a more complete picture of such studies. The first report on a polymer/metal interface by using SFG was published by Lu et al, in which the PMMA/silver (Ag) interface, as a model system, was detected with ssp polarization combination.…”

“…It is important to probe buried polymer/metal interfaces because these interfaces are frequently encountered in microelectronics or anticorrosion coating applications. We have briefly summarized our SFG studies on polymer/metal interfaces in a recent review . Here, we will include more details and present a more complete picture of such studies.…”

Sum Frequency Generation Vibrational Spectroscopy for Characterization of Buried Polymer Interfaces

“…Other review papers of SFG-VS may help readers to gain further understanding of the related fields. [2][3][4][5][6][7][8][9] The Study of Polymer-Water Interface In many situations, polymers are used in contact with water or aqueous solution. In SFG-VS, the polymer/ water interface is among the most extensively studied interfaces since the debut of the technique.…”

“…On the application side, one of the most promising research directions of SFG-VS is to elucidate buried interfacial properties of polymer materials. [2][3][4][5][6][7][8][9] Sum frequency generation vibrational spectroscopy is playing an increasingly important role in revealing molecular behaviors at polymer interfaces to understand interfacial mechanisms such as polymer adhesion, anti-biofouling properties, lubrication, and biocompatibility. Such studies can ultimately help polymer scientists to develop advanced materials with improved performance for science and industry.…”
