Rate-dependent adhesion between opposed perfluoropoly(alkyl ether) layers: dependence on chain-end functionality and chain length
Article Abstract:
A study was conducted to measure adhesion between opposed molecularly thin layers of perfluoropoly(alkyl ether)s on mica, with emphasis on the dependence of the adhesion on chain-end functionality and chain length of the polymer. Experimental results indicated that increases in the adhesion between thin, adsorbed layers of perfluoropoly(alkyl ether) with different chain-end functionality correlated with the logarithmic unloading rate.

Static and dynamic forces between absorbed polyelectrolyte layers (quaternized poly-4-vinylpyridine)
Article Abstract:
Static forces and dynamic shear forces were measure between quaternized poly-4-vinylpyridine layers (QPVP) absorbed onto mica from 1 mM borate buffer with or without added 0.25 M NaCl. At the photoelectrolyte concentration chosen, 0.4 mg mL(super -1), extended layers were formed at all absorption conditions.

Tribology of confined Fomblin-Z perfluoropolyalkyl ethers: role of chain-end chemical functionality
Article Abstract:
A study of static and shear interactions between smooth surfaces separated by molecularly thin films of Fomblin-Z oligomers is presented. Results demonstrate the effect of polar end groups of fluorinated chain nonpolar environment on the films.
