Thermoresponsive polymer desiccants for water harvesting
… yet underutilised source of potable water. Polymeric desiccants are a particularly promising candidate for atmospheric water harvesting given their adaptability and scalability. However, the relative nascency of the field leaves many classes of polymers yet unexplored. This thesis details …

A Thermal Switch from Thermoresponsive Polymer Aqueous Solutions
… switch. Noticing the transition properties of thermoresponsive polymer for drug delivery, its potential in thermal switch can be expected. I used Poly(N-isopropylacrylamide) (PNIPAM) as an example to show the abrupt thermal conductivity change of thermoresponsive polymer solutions below and …

Topographically and Mechanically Tunable PNIPAM Scaffolds
Poly(N-isopropyl-acrylamide) (PNIPAM) is a thermoresponsive polymer with a wide range of biological applications, including drug delivery, biosensing, and tissue engineering. The tunability of the structural and mechanical properties of PNIPAM makes it particularly at- tractive in emulating cell …

Honeycomb structured porous films from different polymer architectures - preparation, mechanism, analysis and post-treatment
… honeycomb structured porous films using various polymer architectures ranging from linear, comb, star polymers and a random copolymer. Four casting methods were designed and applied for the production of structured porous materials. The airflow casting technique, cold-stage casting technique, …

Toward spatial control of gold nanorod surface functionalization
… is presented, relying on layer-by- layer (LbL) polymer wrapping and direct thiol coating of the same parent chromophore structure. Together, these approaches allow for estimated chromophore-particle distances from <1nm to more than 15 nm. Composites were confirmed using conventional nanoparticle …

Self-assembly of cross-linked polymer micelles into complex higher-order aggregates
The creation of complex polymer structures has been one of the major research topics over the last couple of decades. This work deals with the synthesis of (block co-)polymers, the creation of complex and stimuli-responsive aggregates by self-assembly, and the cross-linking of these structures. …

Microcapsule-based techniques for improving the safety of lithium-ion batteries
… Li-ion batteries is demonstrated by depositing thermoresponsive polymer microspheres onto battery anodes. When the internal temperature of the cell reaches a critical value, the microspheres melt and conformally coat the anode and/or separator with an ion insulating barrier, halting Li-ion …

Patterning planar surfaces with motor proteins: Towards spatial control over motile microtubules
… light-to-heat conversion combined with a thermoresponsive polymer layer, was presented as a novel method. Specifically, the conformation of poly(N-isopropylacrylamide) (PNIPAM) molecules in aqueous solution was switched between the swollen state at T < 30°C (protein-repelling …

Photo-crosslinked Surface Attached Thin Hydrogel Layers
Stimuli sensitive polymers and hydrogels respond with large property changes to small physical and chemical stimuli (e.g. temperature, pH, ionic strength). The bulk behavior of these polymers is widely studied and they show an isotropic swelling. However, thin hydrogel layers of polymers on a …

The multifarious self-assembly of triblock copolymers : from multi-responsive polymers and multi-compartment micelles
New ABC triblock copolymers were synthesized by controlled free-radical polymerization via Reversible Addition-Fragmentation chain Transfer (RAFT). Compared to amphiphilic diblock copolymers, the prepared materials formed more complex self-assembled structures in water due to three different …
