Download or read book Tribological and Mechanical Characterizations of Polyelectrolyte Multilayer Nanoassemblies written by Prem Venkatachalam Pavoor and published by . This book was released on 2003 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) To tune the frictional response of PEMs without compromising their wear-retarding behavior, various strategies were explored; these included surface capping with a block co-polymer, in-situ synthesis of silver nanoparticles in the films, and assembly of composites containing PAH and multi-wall carbon nanotubes. The engineered coatings find possible applications in microelectromechanical systems (MEMS) where friction, wear, and stiction can be detrimental to device performance. Nanoindentation was employed to probe the mechanical behavior of these ultra-thin films. It was demonstrated that the modulus and hardness of PAH/PAA PEMs could be tuned as a function of the pH of the polyelectrolyte solutions used for their assembly. The mechanical response of these structures was superior to either parent polyelectrolyte and also commercially used polymeric systems. The mechanical properties were studied at ambient conditions and in the presence of a liquid medium.
Download or read book Advance in Tribology Study of Polyelectrolyte Multilayers written by Yanbao Guo and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This review introduced the preparation and structural characterization of polyelectrolyte multilayers in recent years and also summarized the tribology research progress of the polyelectrolyte multilayers, including tribological properties, surface adhesion characteristics, and wear resistance properties. Statistics analysis indicated that nanoparticles-doped polyelectrolyte multilayers present better friction and wear performance than pristine polyelectrolyte multilayers. Furthermore, the in situ growth method resulted in improved structural order of nanoparticles composite molecular deposition film. In situ nanoparticles not only reduced the molecular deposition film surface adhesion force and friction force but also significantly improved the life of wear resistance. That was due to the nanoparticles that possessed a good load-carrying capacity and reduced the mobility of the polymer-chain segments, which can undergo reversible shear deformation. Based on this, further research direction of in situ nanoparticles molecular deposition film was proposed.
