As lateral compression is applied, microgel particles with different softness exhibit distinct behaviours. Hard microgels (green particles) are pushed away from the air–water interface, whereas soft ones (orange less deformed.

We experimentally investigate the contribution of interchain interaction to interfacial stress and self-assembly microgels at air/water interface. Our results suggest that intercorona penetrations contribute an entropy-driven long-ranged force. The structural parameter binding energy between neighboring are given by using radial distribution function, which further clarifies intercore interactions during 2D phase transition.

Abstract Thin films made of deformable micro‐ and nano‐units, such as biological membranes, polymer interfaces, particle‐laden liquid surfaces, exhibit a complex behavior during drying, with consequences for various applications like wound healing, coating technologies, additive manufacturing. Studying the drying dynamics structural changes soft colloidal thus holds potential to yield valuable insights achieve improvements applications. In this study, interfacial monolayers core‐shell (CS) microgels varying degrees softness are employed model systems investigate their on differently modified solid substrates (hydrophobic vs hydrophilic). By leveraging video microscopy, particle tracking, thin film interference, study shed light interplay between microgel adhesion surfaces immersion capillary forces that arise in film. It is discovered dried replica microstructure can be more accurately achieved hydrophobic substrate relative hydrophilic one, particularly when employing softer colloids opposed harder counterparts. These observations qualitatively supported by experiments pressure balance which allows mimicking controlling process computer simulations coarse‐grained models.

Abstract In the previous study ( Green Chem ., 2023 , 25 3418), highly stretchable and mechanically tough poly(methyl acrylate) (pMA) microparticle‐based elastomers can be formed by drying a microparticle‐containing aqueous dispersion. This discovery has potential to overcome mechanical weakness of industrially produced latex films. However, in 3D‐arranged particle films, structural complexity, such as existence defects, makes it difficult clearly understand relationship between film structure its properties. this study, 2D‐ordered pMA monolayers at air/water interface Langmuir trough are prepared. Under high compression interface, microparticles contact their neighboring particles, resulting successfully transferred onto solid substrate. The monolayer films is linked an increase elastic modulus on substrate evident from local Young's mapping using atomic force microscopy. Thus, with different properties created trough.

In situ interfacial rheology and numerical simulations are used to investigate microgel monolayers in a wide range of packing fractions, ${\ensuremath{\zeta}}_{2D}$. The heterogeneous particle compressibility determines two flow regimes characterized by distinct master curves. To mimic the architecture reproduce experiments, an interaction potential combining soft shoulder with Hertzian model is introduced. contrast bulk conditions, elastic moduli vary nonmonotonically ${\ensuremath{\zeta}}_{2D}$ at interface, confirming long-sought predictions reentrant behavior for Hertzian-like systems.

Deformable colloids and macromolecules adsorb at interfaces, as they decrease the interfacial energy between two media. The deformability, or softness, of these particles plays a pivotal role in properties interface. In this study, we employ comprehensive \emph{in situ} approach, combining neutron reflectometry with molecular dynamics simulations, to thoroughly examine profound influence softness on structure microgel Langmuir monolayers under compression. Lateral compression both hard soft particle induces substantial structural alterations, leading an amplified protrusion microgels into aqueous phase. However, critical distinction emerges: are pushed away from interface, stark contrast ones, which remain steadfastly anchored it. Concurrently, air-exposed side monolayer, lateral flattening surface monolayer. This phenomenon is not observed for monolayer already extremely flat even absence These findings significantly advance our understanding equilibrium phase behavior its effect when used stabilizers responsive interfaces emulsions.
