Sum frequency generation vibrational spectroscopic studies on a silane adhesion-promoting mixtures at a polymer interface

Article Abstract:

Sum frequency generation (SFG) vibrational spectroscopy was used to probe the interface between poly(ethylene terephthalate) with deuterated ethylene glycol subunits (d4-PET) and a silane adhesion-promoting mixture (SAPM) comprised of (3-glycidoxypropyl)trimethoxysilane (gamma-GPS) and a methylvinylsiloxanol (MVS). Such a mixture was found to improve the adhesion of an addition-curing silicone elastomer to a range of plastic and metal substrates.

Conformational changes of fibrinogen after adsorption

Article Abstract:

A study to investigate the adsorption behavior of fibrinogen to two biomedical polyurethanes and a perfluorinated polymer was conducted. Investigation of fibrinogen adsorption revealed that fibrinogen binds and undergoes conformational changes that are highly dependent on the chemical properties of the surface.
