Drop spreading and gelation of thermoresponsive polymers [PDF]

Soft Matter, 2018
Spreading and solidification of liquid droplets are elementary processes of relevance for additive manufacturing. With simple drop spreading experiments of a thermoresponsive polymer solution, we found that the final shape is ruled by the difference between the substrate temperature and the gelation temperature. Unexpectedly, spreading also stops below

Preparation and Properties of Thermoresponsive P(N-Isopropylacrylamide-co-butylacrylate) Hydrogel Materials for Smart Windows

International Journal of Polymer Science, 2019
Thermoresponsive polymers that exhibit phase transition in response to temperature change can be used as material for smart windows because they can control solar light transmission depending on the outside temperature.

Thermoresponsive, Pyrrolidone‐Based Antifouling Polymer Brushes [PDF]

Advanced Materials Interfaces, 2022
AbstractCommonly, modification of surfaces with thermoresponsive polymers is performed using poly(N‐isopropylacrylamide) (poly(NIPAM)). However, integration of poly(NIPAM) with a second polymer to obtain more complex copolymer structures has proven challenging due to inherently poorly controllable polymerization characteristics of acrylamides.

Increasing the Hydrophobic Component of Poloxamers and the Inclusion of Salt Extend the Release of Bupivacaine from Injectable In Situ Gels, While Common Polymer Additives Have Little Effect

Gels, 2022
Various strategies have been applied to reduce the initial burst of drug release and sustain release from poloxamer-based thermoresponsive gels. This work focussed on investigating different formulation approaches to minimise the initial burst of release
