A Multi-scale Investigation of Aqueous Foams Stabilised by PNIPAM Microgels
Joanne Zimmer, Luca Mirau, Kevin Gräff +5
Aqueous foams possess multiple structural motifs across different length scales: macroscopic foam, bubbles, foam films and the air/water interface. In this study, macroscopic foams…
Exploring structure-property relationship on a nanoscale for tailoring films of amphiphilic polymer co-networks
Kevin Hagmann, Carina Schneider, Stephanie Ihmann +2
Amphiphilic polymer co-networks (APCNs) provide a large toolbox for tuning coatings important for applications such as bio-interfaces. Therefore, we investigate the influence of ne…
Jetting with gels: Soft microgel networks stabilize and extend nozzle-free water jets
Atieh Razavi, Mehrzad Roudini, Andreas Winkler +4
The stability of high-speed liquid jets is crucial for applications ranging from precision printing to needle-free drug delivery, yet it is fundamentally limited by capillary-drive…
Ion-specific Stability of Gold Nanoparticle Suspensions
Philipp Ritzert, Alexandra Striegel, Regine von Klitzing
Gold nanoparticles (AuNPs) play an important role in fundamental research and development due to their versatile applications and biocompatibility. This study addresses the aging o…
Conceptualizing flexible papers using cellulose model surfaces and polymer particles
Cassia Lux, Sabrina Kerz, Catarina C. Ribeiro +7
Cellulose, as a naturally abundant and biocompatible material, is still gaining interest due to its high potential for functionalization. This makes cellulose a promising candidate…
Influence of Dopamine Methacrylamide on swelling behaviour and nanomechanical properties of PNIPAM microgels
Sandra Forg, Xuhong Guo, Regine von Klitzing
The combination of the catechol-containing co-monomer dopamine methacrylamide (DMA) with stimuli-responsive microgels such as poly(N-isopropylacrylamide) (PNIPAM) bears a huge pote…
Impact of Ultrasound on the Motion of Compact Particles and Acousto-responsive Microgels
Sebastian Stock, Regine von Klitzing, Amin Rahimzadeh
In this study, we investigate dynamic light scattering (DLS) from both randomly diffusing silica particles and acousto-responsive microgels in aqueous dispersions under ultrasonic…
Frequency-dependent Ultrasonic Stimulation of PNIPAM Microgels in Water
Atieh Razavi, Matthias Rutsch, Sonja Wismath +3
As a novel stimulus, we used high-frequency ultrasonic waves to provide the required energy for breaking hydrogen bonds between Poly(N-isopropylacrylamide) (PNIPAM) and water molec…
Amphiphilic co-polymer network gel films based on tetra-poly(ethylene glycol) and tetra-poly(ε-caprolactone)
Kevin Hagmann, Carolin Bunk, Frank Böhme +1
In order to allow the simultaneous transport of hydrophilic and hydrophobic substances, polymeric networks with finely distributed hydrophilic and hydrophobic components are very s…
