Due to the low entropy of mixing, miscibility gaps are often observed for polymer solutions. Many polymers are known that show UCST or LCST behavior in organic solvents. Examples for organic polymer solutions with UCST are polystyrene in cyclohexane, polyethylene in diphenylether or polymethylmethacrylate in acetonitrile. An LCST is observed for, e.g., polypropylene in n-hexane, polystyrene in butylacetate or polymethylmethacrylate in 2-propanone. WebbThermo-responsive fluorescent materials are promising candidates for the development of fluorescent thermometers, biological sensors and biomedicine. Since the interesting phenomenon of aggregation-induced emission (AIE) was first defined by Tang in 2001, it has provided a wonderful platform for development of efficient luminescent materials. selling t6 heavy crafting bag

WebbFor example, poly ( N -isopropylacrylamide) (PNIPAM) is a promising macromolecule in thermo-responsive bioadhesives with a low critical solution temperature (LCST) of about 32 °C. According to the reports, hydrophilic PNIPAM reversibly alters to a hydrophobic state by increasing the external temperature until LCST. WebbThe DLS study revealed that temperature has little effect on micelle size. Poly(dodecyloxyethylene phosphate)s, based on PEG 400 represent stimuli-responsive polymer. At 25 °C the polymer did not create micelles, but increasing the temperature to at least 30–40 °C started self-assembly. WebbFör 1 timme sedan · Although ultrasound- and thermo-sensitive hydrogels are responsive to certain ultrasound modalities, they differ in how they respond to external stimuli. Ultrasound-responsive hydrogels are capable of being stimulated by more than one type of stimulation force through ultrasound [42]. selling t-shirts on shopify
