Novel coupling agents for mineral-reinforced polyamides

Novel Phenylethynyl Imide Silanes as Coupling Agents for Titanium Alloy

The durability of titanium (Ti) alloys bonded with high temperature adhesives such as polyimides has failed to attain the level of performance required for many applications. The problem to a large part is attributed to the instability of the surface treatment on the Ti substrate. Although Ti alloy adhesive specimens with surface treatments such as chromic acid anodization, Pasa-Jell, Turco, et...

Enhancement of interfacial properties of basalt fiber reinforced nylon 6 matrix composites with silane coupling agents

In this work solution surface treatment was applied for producing basalt fiber reinforced PA6 matrix composites. Beyond scanning electron microscopy, static and dynamic mechanical tests, dynamic mechanical analysis of composites was used for qualifying the interfacial adhesion in a wide temperature range. The loss factor peak height of loss factor is particularly important, because it is in clo...

Novel Anodic Polyelectrochromic Aromatic Polyamides Containing Pendent Dimethyltriphenylamine Moieties

Two series of novel aromatic polyamides containing pendent dimethyltriphenylamine moieties were prepared based on N,N-bis(4-aminophenyl)-N′,N′-di(4-methylphenyl)-1,4-phenylenediamine (4) and N,Nbis(4-carboxyphenyl)-N′,N′-di(4-methylphenyl)-1,4-phenylenediamine (4′). These compounds with similar structures were successfully synthesized by amination reactions of 4-amino-4′,4′′-dimethyltriphenylam...
