Fatigue crack initiation and propagation in polyamide‐6 and in polyamide‐6 nanocomposites

Polymer Composites, 2004
AbstractRecent developments in polymer nanocomposites have led to improvements in conventional short‐term, but the long‐term mechanical properties have received little attention. The objective of the present study was to characterize the effect of nanoparticles on the fatigue crack initiation and propagation mechanisms and on the fatigue properties of ...

Synthesis of Polyamide 6-block-Vinyl Polymers Using New Polyamide 6 Radical Initiators [PDF]

Polymer Journal, 1999
Two polyamide 6 (PA6) radical initiators (PA6ini), AI and AIA types (A : PA6 segment, I : azo group), were prepared from 4,4′-azobis-2-cyanopentanoyl chloride and PA6 prepolymers having controlled average molecular weights. Various PA6-block-vinyl polymers were synthesized by radical polymerizations of vinyl monomers, such as styrene, methyl ...

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.
