Electrospun Poly(N-isopropylacrylamide)/Ethyl Cellulose Nanofibers as Thermoresponsive Drug Delivery Systems [PDF]

, 2016
Fibers of poly(N-isopropylacrylamide) (PNIPAAm), ethyl cellulose (EC), and a blend of both were successfully fabricated by electrospinning. Analogous drug-loaded fibers were prepared loaded with ketoprofen (KET).

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
