Use of Atmospheric-Pressure Plasma Jet for Polymer Surface Modification available in PDF, EPUB and Kindle. Atmospheric-pressure plasma jets (APPJs) are playing an increasingly important role in materials processing procedures. Plasma treatment is a useful tool to modify surface properties of materials, especially polymers. Plasma reacts with polymer surfaces in numerous ways thus the type of process gas and plasma conditions must be explored for chosen substrates and materials to maximize desired properties. This report discusses plasma treatments and looks further into atmospheric-pressure plasma jets and the effects of gases and plasma conditions. Following the short literature review, a general overview of the future work and research at Los Alamos National Laboratory (LANL) is discussed.

Atmospheric Pressure Plasma Treatment of Polymers available in PDF, EPUB and Kindle. An indispensable volume detailing the current and potential applications of atmospheric pressure plasma treatment by experts practicing in fields around the world Polymers are used in a wide variety of industries to fabricate legions of products because of their many desirable traits. However, polymers in general (and polyolefins, in particular) are innately not very adhesionable because of the absence of polar or reactive groups on their surfaces and concomitant low surface energy. Surface treatment of polymers, however, is essential to impart reactive chemical groups on their surfaces to enhance their adhesion characteristic. Proper surface treatment can endow polymers with improved adhesion without affecting the bulk properties. A plethora of techniques (ranging from wet to dry, simple to sophisticated, vacuum to non-vacuum) for polymer surface modification have been documented in the literature but the Atmospheric Pressure Plasma (APP) treatment has attracted much attention because it offers many advantages vis-a-vis other techniques, namely uniform treatment, continuous operation, no need for vacuum, simplicity, low cost, no environmental or disposal concern, and applicability to large area samples. Although the emphasis in this book is on the utility of APP treatment for enhancement of polymer adhesion, APP is also applicable and effective to modulate many other surface properties of polymers: superhydrophilicity, superhydrophobicity, anti-fouling, anti-fogging, anti-icing, cell adhesion, biocompatibility, tribological behavior, etc. The key features of Atmospheric Pressure Plasma Treatment of Polymers: Address design and functions of various types of reactors Bring out current and potential applications of APP treatment Represent the cumulative wisdom of many key academic and industry researchers actively engaged in this key and enabling technology

Download and read online ebook Plasma Modification of Polyolefins write by N. S. Baneesh. This book was released on 2021-11-22. Plasma Modification of Polyolefins available in PDF, EPUB and Kindle. This book addresses plasma modification of polyolefin surfaces. It comprises 21 chapters divided into three major sections. The first section covers the different techniques used for plasma modification of polyolefin surfaces and the effects of various gases as a surrounding medium, while the second provides a detailed analysis of the physics and chemistry of plasma modification and discusses various innovative characterization techniques, as well as ageing of the modified surface. It focuses on the analysis of changes in polymers’ surface chemistry using various spectroscopic techniques, and of changes in their surface morphology after plasma treatment using optical microscopy, electron microscopy and atomic force microscopy. In addition, it provides detailed information on the characterization of modified polymer surfaces. The book’s third and last section covers a range of applications of plasma-modified polyolefin surfaces varying from the packaging industry to the biomedical field, and shares valuable insights on the lifecycle analysis of plasma modification and modified surfaces.

Surface Modification of Cyclic Olefin Polymers Using Atmospheric Pressure Jet available in PDF, EPUB and Kindle. The design and development of the plasma pressure jet is used throughout the thesis. The plasma jet's key components are discussed. Helium, argon, nitrogen, and air plasma were used to study the surface activation and bonding of cyclic olefin polymers. The plasma gas had a temperature less than 50 °C, making it suitable for polymer processing. The substrates were treated between 3 to 20 mm from the plasma exit. Air, as the plasma jet's feeding gas, creates a surface wettability of less than 10°. Water contact angle (WCA), scanning electron microscopy (SEM), atomic force microscopy (AFM), and infrared spectroscopy (IR) were used to characterise the substrate surface properties. This study establishes atmospheric pressure plasma as a cost-effective method for making cyclic olefin polymers hydrophobic and super hyderophilic. Secondly, design expert V12 software was used to optimize the APPJ operating parameters to obtain the lowest COP water contact angle with the lowest pricing. More research is required to optimise the polymer's surface and reduce the number of repetitive experiments. Therefore, the plasma jet was detailed to better facilitate understanding. Voltage and current probes were used for electrical measurements, and optical characterisation was performed using optical emission spectroscopy. Hydrophobic recovery of polymers is a concern in a variety of applications, most notably microfluidic devices. The work presented in Chapter 5 resulted in a stable surface that remained stable for more than 60 days and was partially stable for approximately 180 days. Finally, we modified the surface of disposable glass for biosensor applications. In order to improve the optical properties, the gold of different thickness can be tailored in this work by varying plasma jet parameters. The surface treated was characterised using UV-VIS spectroscopy and scanning electron microscopy. Although the results were not suitable for biosensor applications, the experiment was worthwhile.
