“…Different methods for the graft copolymerization of PNIPAAm have been described: hydrogel copolymer grafted onto solid surfaces; photo-induced grafting copolymerization; plasma-induced grafting copolymerization; irradiation copolymerization. [85,86] Regarding the medium, solution and bulk polymerizations are applied for homogeneous phases while emulsion polymerization is performed for heterogeneous phases. PNIPAAm hydrogels obtained using the first two methods exhibit random particle size distribution, whereas the last method allows to modulate the size from micro-to nanoscale.…”

Temperature‐sensitive (thermosensitive) hydrogels, which are part of the family of stimulus‐sensitive hydrogels, consist of water‐filled polymer networks that display a temperature‐dependent degree of swelling. Thermosensitive hydrogels, which can undergo phase transition or swell/de‐swell as temperature changes, have great potential in various technological and biomedical purposes for a number of reasons: their temperature response is reversible, hydrogels are stable and easy to prepare, they can be biocompatible and also be suitably combined with other organic and inorganic materials, resulting in new materials with outstanding properties. Among thermosensitive hydrogels poly(N‐isopropylacrylamide) (PNIPAAm) is the most extensively studied because it brings together the best properties of these materials. Consequently, in the past few years, a wide number of applications and new chemical processes to prepare PNIPAAm and their derivatives are being proposed. The objective of this review is to summarize the fundamentals of thermosensitive hydrogels and recent advances in preparation and both technological and biomedical applications of thermosensitive hydrogel, with a special focus on PNIPAAm and their derivatives. Special attention has been given to the discussion of challenges and future research perspectives based on new horizons not yet considered.

“…Neste método, quando a irradiação é realizada em atmosfera inerte, os radicais livres são formados e permanecem disponíveis para as reações de recombinação. Entretanto, se a irradiação for realizada no ar, os radicais livres reagem com o oxigênio para formar espécies de peróxidos e hidroperóxidos [21] que são decompostos termicamente para iniciar a polimerização dos enxertos de monômero na reação em cadeia [22,54]. A quantidade, estabilidade e durabilidade desses radicais dependem de parâmetros como o tipo de polímero, bem como das condições de irradiação e armazenamento do polímero irradiado.…”

Dedico esta tese de doutorado à minha querida irmã (in memoriam) que, mesmo ausente fisicamente entre nós, tenho plena certeza de que tem olhado por mim e me protegido desde sua partida. Esta tese é a garantia de que alcancei o mais alto grau de formação educacional, conforme prometido. Além disso, dedico este trabalho à Ana Laura G.Biancolli, agradecendo por todo esforço, coragem, apoio e dedicação que foram fundamentais no desenvolvimento desta tese. Sou grato e tenho orgulho da amizade construída durante meu doutoramento. Tenho plena convicção de que você estará fortalecida ao final desse processo tortuoso."Science is a collaborative effort.The combined results of several people working together is often much more effective than could be that of an individual scientist working alone"
