Synthesis and Characterization of Pyrrole Based Adhesion Promoter Systems on Oxide Substrates
… were designed and successfully synthesized as adhesion promoters. These new derivatives were studied for their adsorption behavior on oxide substrates and chemical or electrochemical deposition of polypyrrole over modified oxide surface or electrodes. Several analytical techniques such as …

Polythiophene als sensitive Filme in chemischen Sensoren
… the first step the substrate is coated with an adhesion promoter and in a second step the chemical surface polymerisation of the monomer is performed. This deposition method was combined with new patterning techniques. The basis of this process is the patterned application of the adhesion …

Korrosionsschutz von Eisenwerkstoffen durch intrinsisch leitfähige Polymere
… with 2(3-thienyl)ethylphosphono acid used as adhesion promoter (AP). The corrosion protection properties of such films are investigated with and without topcoats in some corrosive media. Possible protection mechanisms of ICP could be discussed.

Diffusion Barriers/Adhesion Promoters. Surface and Interfacial Studies of Copper and Copper-Aluminum Alloys
… between copper and the diffusion barrier/adhesion promoter. The behavior of copper sputter-deposited onto sputter-cleaned tantalum nitride is investigated. The data show that copper growth on tantalum nitride proceeds with the formation of 3-D islands, indicating poor adhesion …

Silver-magnesium thin film interactions in an oxidzing ambient
… drawbacks are the difusion of Ag into SiO2, poor adhesion to SiO2, and corrosion of silver when exposed to ambients such as H2S and C}i. To overcome these stability problems, we need diffusion barriers to prevent interdifusion of Ag into SiO2, an adhesion promoter to improve adherence, and a …

Relationship between molecular structure and surface properties of self-assembled monolayers
… monolayers are investigated for use as an adhesion promoter for metal substrates, and for corrosion protectors of the metal surface. Gold substrates modified by adsorption of 3- and 4-aminothiophenol monolayers, 3- and (4-mercaptophenyl) phthalimide (MPP) monolayers, and by reaction of the …

Fundamental Analysis of Wood Adhesion Primers
Hydroxymethyl resorcinol (HMR) is an effective adhesion promoter (primer) for wood bonding; it dramatically improves adhesion and enhances bond durability against moisture exposure. In an effort to improve understanding of the HMR mechanism of action, this work compared HMR with two other chemical …

Surface analysis of sodium oleate coated poly (ethylene terephthalate) films
… alter surface properties resulting in improved adhesion and wettability. The objective of the present work was to demonstrate the applicability of surface-sensitive techniques in the analysis of polymer films coated with thin overlayers. The surface or interphase region of sodium oleate coated …

Advancing characterization techniques for structure-property determination of in-situ lignocelluloses
… domains. Finally the effects of a wood-adhesion promoter (hydroxymethyl resorcinol, HMR) on in-situ wood polymers are studied to elucidate the still unresolved HMR-lignocellulose interactions. DMA, creep-TTS and 2H NMR reveal that HMR increases the crosslink density and restricts the …

Functional coatings deposited by an Atmospheric Pressure Plasma Jet (APPJ) system over Thermoplastic Elastomer (TPE) substrates
… irregular distribution of fibers, poor adhesion and superhydrophilic character are the main drawbacks. Since TPE is a heat-sensitive material, an Atmospheric Pressure Plasma Jet (APPJ) system with a Dielectric Barrier Discharge (DBD) was used in this thesis. During the first group of …

Study of Interactions Between Diffusion Barrier Layers and Low-k Dielectric Materials for Copper/Low-k Integration
… requires the development of diffusion barrier/adhesion promoter materials that provide excellent performance in preventing the diffusion and intermixing of Cu into the adjacent dielectrics. The integration of Cu with low-k materials may decrease RC delays in signal propagation but pose …

Photo-crosslinked Surface Attached Thin Hydrogel Layers
… to the surface was achieved through an adhesion promoter. Swelling behavior of the thin polymer layers was thoroughly investigated by Surface Plasmon Resonance (SPR) Spectroscopy and Optical Waveguide Spectroscopy (OWS). SPR and OWS gave a wide range of information regarding the film …

Synthesis and Characterization of Thin films of Novel Functionalised 2,5-Dithienylpyrrole Derivatives on Oxide Substrates
… conducting polymers. The problem of poor adhesion of the electrochemically deposited conducting polymers was the main focus of this work. This easy peeling of the PPY layer from the oxide substrate was circumvented by design of novel adhesion promoters, which compatibilise the two …

An Experimental Investigation of Electrowetting Modulated Nucleate Boiling
Electrowetting (EW) has drawn significant research interests in droplet-based microfluidics, and most applications focus on electronic displays, lab-on-a-chip devices and electro-optical switches, etc. In this work, we report a novel application of EW in enhancing nucleate boiling heat transfer. …
