Effect of temperature on the air–water surface mechanical behavior of water-spread block copolymer micelles

Abstract

In the pursuit of the development of a first-in-kind polymer lung surfactant (PLS) therapeutic, whose effects are biophysical in nature, a comprehensive understanding of the factors affecting the air-water surface...

Surface Mechanical Behavior of Water-Spread Poly(styrene)–Poly(ethylene glycol) Cylindrical Micelles at the Air–Water Interface

“…A previous study found that the optical film thickness sharply increases when the monolayer transitions into collapse or wrinkle structure. 29 In the 50w sample, this elevation in t corresponded to the initiation of micelle film collapse at a specific Π of 61.6 mN/m and a corresponding A of 153.7 cm 2 . For the 60w and 70w samples, the rise in t took place at Π values of 58.4 and 54.9 mN/m and corresponding A values of 192.5 and 216.4 cm 2 , respectively, prior to the ultimate collapse regime.…”
