“…To characterize the hydrogels, the most common techniques used are water uptake [Lohakan et al, 2010;; mechanical properties [Baker et al, 2010;Jiang et al, 2010;Xu et al, 2010]; scanning electron microscopy (SEM) [Moura et al, 2009;Ferrer et al, 2010;Gao et al, 2010;Li et al, 2010;Zhao et al, 2010]; Fourier transform infrared (FTIR) spectroscopy [Kim et al, 2010;; nuclear magnetic resonance (NMR) [Yin et al, 2010]; differential scanning calorimetry (DSC) [Castelli et al, 2008;Rao et al, 2010]; thermogravimetric analysis (TGA) [Rodkate et al, 2010]; structural properties [Panic et al, 2010] through average molar mass between crosslinks (M c ), crosslink density (q), and number of elastically effective chains, completely included in a perfect network, per unit volume (V e ); and controlled release of drugs [Koutroumanis et al, 2010;Liu & Lin, 2010;Sajeesh et al, 2010;Tanigo et al, 2010]; and agrochemicals [Saraydin et al, 2000;Bajpai & Giri, 2003;Bajpai et al, 2006;Wang et al, 2007;Pourjavadi et al, 2009].…”

“…A poliacrilamida (poli-2-propenamida) é formada por unidades de acrilamida (Figura 6), as quais a constituem em um polímero termosensível amplamente utilizado para síntese de hidrogéis (BURILLO & OGAWA, 1986;GUILHERME et al, 2003;SANCHEZ-DÍAZ et al, 2006;BARDAJEE et al, 2008;LI et al, 2008;ZHAO et al, 2010, CLOUTIER et al, 2013. Sua massa molar é de 2,5.…”
