Stable superhydrophobic organic-inorganic hybrid films by electrostatic self-assembly

Article Abstract:

Stable organic-inorganic hybrid films, which have superhydrophobic character, are fabricated through layer-by-layer (LBL) deposition of poly(allylaminehydrochloride) (PAH) and ZrO2 nanoparticles coated with poly(acrylic acid) (PAA), allowing facile control of surface roughness and hydrophobicity. The proposed method can also be used to fabricate PAH/PAA-coated ZrO2 nanocomposite coatings with very good chemical and mechanical durability for various applications.

Conformational changes of pyrene-labeled polyelectrolytes with pH: Effect of hydrophobic modifications

Article Abstract:

The structural changes of pyrene-labeled and unlabeled poly(maleic acid/octyl vinyl ether) (PMAOVE) and poly(maleic acid/octyl vinyl ether) (PMAMVE) with changes in pH are examined to interpret uncoiling or swelling of the polymeric chains with pH. The results show that an increase in pH ionizes a number of COOH groups on both PMAMVE and PMAOVE that leads to the stretching or swelling of the polymers.

Pearl-necklace structures in annealed polyelectrolytes

Article Abstract:

The behavior of annealed polyelectrolytes is studied with the help of (semi-)grand canonical Monte Carlo simulations of a polyelectrolyte chain of length N. The conformations with regard to parameters u, tau and mu are investigated and in which conditions pearl-necklace-like structures are stable are explored.
