“…As expected, Fe‐alg/GO nanocomposite film reached tensile strength of 161.8 ± 24.2 MPa and elastic modulus of 5.86 ± 0.64 GPa, Ba‐alg/GO and Ca‐alg/GO nanocomposite films reached tensile strength of 137.6 ± 22.3 MPa and 122.3 ± 18.5 MPa and elastic modulus of 3.94 ± 0.51 GPa and 3.58 ± 0.42 GPa, respectively. In addition, the elongations at break of Na‐alg/GO nanocomposite films were lower than M‐alg/GO which agreed with the work by Russo et al …”

Association of a method of the incorporation of graphene oxide (GO) into sodium alginate (Na‐alg) polymer matrix with a method of the use multivalent cations crosslinker was put forward to synthesize novel Na‐alg/GO nanocomposite films. The structures, morphologies, and the properties of Na‐alg/GO films were characterized by Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FE‐SEM), thermogravimetric analysis (TGA), and tensile tests. The results revealed that the interlayer distance of GO sheets increased from 0.83 nm to 1.08 nm after assembling with Na‐alg, and Na‐alg inserted into GO layers crosslinking with multivalent cations increased the interlayer distance further. Ionic crosslinking significantly enhanced thermal and mechanical properties of Na‐alg/GO nanocomposite films. In particular, Fe3+ led to Na‐alg/GO nanocomposite films of significantly higher tensile strength and modulus than Ca2+ and Ba2+. The excellent thermal and mechanical properties of these novel Na‐alg/GO nanocomposite films may open up applications for Na‐alg films. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…However, SA films are hydrophilic and soluble matrices, and the crosslinking process with polyvalent cations has been used to improve their water resistance, mechanical resistance, barrier properties, cohesiveness, and rigidity (Crossingham, Kerr, & Kennedy, 2014;Pavlath, Gossett, Camirand, & Robertson, 1999;Rhim, 2004;Russo, Abbate, Malinconico, & Santagata, 2010;Russo, Malinconico, & Santagata, 2007;Silva et al, 2009). Moreover, the crosslinking process and properties of SA films are strongly dependent on the method used for the introduction of the crosslinking ion Ritcharoen, Supaphol, & Pavasant, 2008;.…”

Polysaccharides, such as alginates, are already being used as carriers for drug delivery. The physicochemical and biological properties of alginates may be affected via irradiation and thermal treatments. To explore and compare effects of two kinds of sterilization methods, gamma irradiation and moist heat, on sodium alginate (SA), physicochemical and biological properties of SA powder and solutions were investigated after sterilization. Human umbilical vein endothelial cells (HUVEC) was used to assess the cytotoxicity of the SA after sterilization. The research showed that 25 kGy gamma ray can effectively sterilize microorganism. Both gamma irradiation and moist heat hardly affect the native pH of SA. Compared to irradiation sterilization, moist heat sterilization showed smaller changes in intrinsic viscosity for all SA samples and lead to less glycosidic bond breaking of SA powders. The moist heat sterilization can cause the main chain scission and double bonds formation of the SA solutions. Cytotoxicity studies demonstrated that sterilized SA powers and SA solutions treated by gamma ray sterilization can increase the viability of HUVEC. However, SA solutions treated by moist heat sterilization were found to present severe cytotoxicity. The research results may provide interesting future advancements toward the development of SA-based products for biomedical applications.
