The correct interpretation of light scattering data requires knowledge of the extent to which multiple scattering contributes to the measured signal. Generally, this information cannot easily be obtained in conventional light scattering experiments.

Die zentrale Frage der Klebtechnik ist heute nicht mehr, wie eine gute, direkt nach der Aushartung des Klebstoffes gemessene Anfangshaftung erreicht werden kann. Dies ist in der Regel moglich, selbst bei geolten Rohbaublechen in der Automobilindustri

The formation of an interphase between an epoxy resin and an urethane is shown. The interphase is formed by the reaction of isocyanate groups with the hydroxyl groups of the already cured epoxy resin. The network density of the epoxy resin was contro

The scope of applications for electrically conductive adhesives increases continuously requiring new and improved properties. In general, isotropic conductivity is achieved by loading a high resistive polymer (mainly epoxy resins) with 70-80 wt% of m

Thin films of 2,4,6-tris-(2,2-bisphenyl-propane)-1,3,5-triazine (p-CPC-trimer), deposited on clean, oxidized and H20-saturated Si(100) surfaces, have been investigated by X-ray Photoelectron Spectroscopy (XPS), Ultraviolet Photoelectron Spectroscopy

The influence of CO 2 laser radiation on the surface properties of poly(ether ether ketone) (PEEK) is shown. The influence on the surface chemistry is nearly negligible, but the roughness increases and the crystallinity in the surface region decrease

Ultrathin films of a prepolymer of the dicyanate of bisphenole A were made by dip-coating on commercial silicon wafers. The initial stages of film formation could be characterized in detail by AFM (atomic force microscopy) in the tapping mode and in

Ultra-thin films of a dicyanate bisphenol A prepolymer on aluminium or silicon substrates are studied as a model for an adhesive interphase. AFM shows structural details of the films with a lateral resolution from some 10 nm up to a few microns. Subs

The birth and growth of ultrathin polymer films out of solution were studied by means of atomic force microscopy (AFM). The system investigated consisted of a model substance for a curable high-temperature adhesive (a prepolymer of the dicyanate of b

FTIR reflection spectroscopy was used to characterize thin films of a cyanurate prepolymer on evaporated aluminium and on silicon single crystal wafers. Both substrates are covered by their native oxides. The optical function of the prepolymer is der
