    Notes: Abstract Two-dimensional mixtures were studied between a polymer, polymethylmethacrylate (PMMA) which has at the water-air interface its chains distributed almost parallel to that interface, and two esters, methylstearate (MS) and methyloleate (MO), characterized by having the same chain length but a different interface orientation. It was shown that the main interactions occurring are those between the hydrophobic chains, and consequently that compatibility between the substances depends essentially on their having the same interface orientation.

    Monolayers of stearic acid esters at the air-water interface: two-dimensional phases and miscibility (1986)
    Springer

    Details
    ISSN: 1435-1536
    Keywords: Monolayers ; air-water interface ; two-dimensional phases ; two-dimensional miscibility ; stearic acid esters

    Notes: Abstract Monolayers of three stearic acid esters, methyl-stearate, propyl-stearate and butyl-stearate, were studied at the air-water interface in the 15–35 °C temperature range. To investigate the surface phases of these esters spread at the air-water interface, some state equations were fitted with the experimental data taken from the isotherms. Surface potential measurements were carried out to obtain information on the molecular orientation. The interfacial orientation and distribution was discussed in relationship to the surface phases present. Ellipsometric measurements were made to determine the thicknesses. The two-dimensional miscibility for the mixture methyl-stearate/butyl-stearate was also studied: surface free energies, enthalpies, and entropies of mixing were computed. The results obtained confirmed previous deductions about the role of the hydrophobic chains in determining the two-dimensional miscibility when they have the same interfacial orientation.

    Polylaurylmethacrylate in bidimensional mixtures with low and high molecular weight substances: effect of the chain mobility on mutual miscibility (1986)
    Springer
    Colloid & polymer science 264 (1986), S. 241-247 
    Details
    ISSN: 1435-1536
    Keywords: Monolayers ; air-water interface ; bidimensional mixtures ; polylaurylmethacrylate ; polyoctadecylmethacrylate ; polymethylmethacrylate ; stearic acid

    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Bidimensional two-component mixtures of polylaurylmethacrylate with polyoctadecylmethacrylate, polymethylmethacrylate and stearic acid were studied in the 15–30 °C temperature range at the air-water interface, in order to determine the effect of the “state” of the hydrophobic side chains on the bidimensional miscibility. We showed that bidimensional miscibility depends on whether the two components have the same interfacial orientation, and that the “fluidity” of the polymer side chains also plays a very important role.

    Macromolecular conformations at the water-air interface: Interactions between alpha and beta conformations of polypeptides (1988)
    Springer
    Colloid & polymer science 266 (1988), S. 783-792 
    Details
    ISSN: 1435-1536
    Keywords: Macromolecules ; air-water interface ; polypeptides ; macromolecular conformations ; monolayers
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Bidimensional miscibility between alpha and beta conformations of polypeptides was investigated at the water-air interface in the 15°–30°C temperature range. The polypeptides were poly-γ-methyl-L-glutamate (PGMG), poly-γ-benzyl-L-glutamate (PGBG) and poly-γ-benzyl-L-aspartate (PBBA). The polypeptide conformations, alpha or beta, were checked by IR spectroscopy using the MIR technique. The spreading isotherms for mixed monolayers alpha-PGMG/alpha-PGBG and beta-PGMG/beta-PBBA showed bidimensional miscibility both for alpha-alpha and beta-beta mixtures. For the alpha-alpha system, attractive interactions among the polypeptide alphahelices were found (ΔGmix〈0) and the driving factor appeared to be the entropic one (packing). Compressibility moduli and surface potential measurements showed a “fluidification” effect of alpha-PGBG on mixed monolayers. In the case of beta-beta mixed monolayers, ideal behaviour was observed and no “fluidification” effect detected. Scanning electron micrographs made on collapsed monolayers showed hexagonal structures for alpha-alpha mixtures and no well-defined or characterized features for the beta-beta system.
