Thermoresponsive Microgel-Based Free-Standing Membranes: Influence of Different Microgel Cross-Linkers on Membrane Function

Maxim Dirksen et al.

Summary: This study explores the production of thermoresponsive, free-standing microgel membranes using N-isopropylacrylamide (NIPAM) and the UV-sensitive comonomer 2-hydroxy-4-(methacryloyloxy)benzophenone (HMABP). The use of different cross-linkers in microgel syntheses allows for variations in the network structure and swelling behavior. The incorporation of the comonomer is influenced by the choice of cross-linker, which is crucial for the subsequent photochemical membrane formation.

Changes in the Form Factor and Size Distribution of Nanogels in Crowded Environments

Tom Hoefken et al.

Summary: Particle size disparities can inhibit crystallization, but soft deformable nanogels have the ability to change the size of larger particles and crystallize even with high initial size-polydispersity. Experimental results using neutron scattering with contrast variation show an increase in the parameter describing size-polydispersity for individual nanogels in crowded environments, which is often interpreted as deformation. Computer simulations confirm this qualitative increase of the parameter with increasing particle deformation. Furthermore, the analysis reveals that the size disparities between nanogels do not significantly increase, but their shapes vary greatly.

How Softness Matters in Soft Nanogels and Nanogel Assemblies

Andrea Scotti et al.

Summary: This paper introduces methods to quantify the concept of softness in nanoscience and related parameters, and reviews the latest research on soft colloids. It also discusses the influence of different synthesis routes on the softness of nanogels, as well as the phase behavior and flow properties of concentrated nanogel solutions.

In-situ study of the impact of temperature and architecture on the interfacial structure of microgels

Steffen Bochenek et al.

Summary: This study utilized neutron reflectometry to investigate the structure and responsiveness of microgels at the air-water interface. The results revealed that temperature only affects the portion of microgels in water, while the softness of the microgels has the strongest effect on their ability to protrude into the air.

Resolving the different bulk moduli within individual soft nanogels using small-angle neutron scattering

Judith Elizabeth Houston et al.

Summary: This study determines the bulk modulus, K, for different morphological parts of nanogels and investigates its changes with compression. The researchers use a partially deuterated polymer and small-angle neutron scattering to accurately determine the form factor of the particles. The results reveal significant differences in softness, compressibility, and evolution of K between the nanogel shell and the rest of the particle, depending on the amount of cross-linker used in their synthesis.

Stiffness Tomography of Ultra-Soft Nanogels by Atomic Force Microscopy

M. Friederike Schulte et al.

Summary: This study investigates extremely soft temperature-sensitive ultra-low cross-linked nanogels adsorbed to the solid/water interface using atomic force microscopy. The nanogels exhibit extraordinary disk-like and homogeneous structure, softer than polymer brushes, and can be switched between ultra-soft and very stiff states on demand. Force Volume mode measurements provide detailed evaluation of their overall shape and internal structure in three dimensions.

Characterization of the volume fraction of soft deformable microgels by means of small-angle neutron scattering with contrast variation

Andrea Scotti

Summary: The volume fraction occupied by colloids in suspension determines their phase behavior, with soft compressible colloids presenting challenges in accurately defining their real volume due to their surface fuzziness and ability to interpenetrate with neighboring particles.

Osmotic pressure of suspensions comprised of charged microgels

A. Scotti et al.

Summary: The osmotic pressure of both ionic and neutral microgel solutions is primarily determined by the behavior of free ions leaving the microgel periphery to maximize entropy, rather than the translational degrees of freedom of the microgels themselves. Microgels are energetically favorable to maintain a constant volume without significant deswelling up to a certain concentration. The concentration at which deswelling begins weakly depends on the crosslinker concentration, which impacts microgel size; this can be explained by examining the relationship between osmotic pressure, microgel bulk modulus, and particle size.
