“…Cross-linked networks of synthetic polymers such as polyethylene oxide (PEO) (Khoylou & Naimian, 2009), polyvinyl pyrollidone (PVP) (Razzak et al, 2001), polylactic acid (PLA) (Palumbo et al, 2006), , polyacrylic acid (PAA) (Onuki et al, 2008), polymethacrylate (PMA) (Yang et al), polyethylene glycol (PEG) (Singh et al), or natural biopolymers (Coviello et al, 2007) such as alginate, chitosan, carrageenan, hyaluronan, and carboxymethyl cellulose (CMC) have been reported. The various preparation techniques adopted are physical crosslinking (Hennink & Nostrum, 2002), chemical cross-linking (Barbucci et al, 2004), grafting polymerisation (Said et al, 2004), and radiation cross-linking (Fei et al, 2000;Liu et al, 2002b).…”

“…The two monomers used have very fair reputation as non-toxic and biocompatible materials 18 . Hydrogels based on poly (vinylpyrrolidone) have been applied successfully as local dressings on wound treatments, such as burns, skin's ulceration and postoperative dressings 19 or controls release system for drug delivery 20,21 because of their biocompatibility with the human body. Moreover, polyacrylic acid is known to be a good mucoadhesive and may increase the transit time of formulation, in drug delivery systems 22 .…”

Hydrogels have been extensively explored for biomedical applications due to their ability to absorb high water content in its structure, which gives excellent biocompatibility. This work aims at obtaining biocompatible hydrogels with potential for use in increasing the mechanical strength of bone substitutes, or controlled drug release. Poly (N-vinyl-2-pyrrolidone) hydrogels were prepared by free radical polymerization with and without the addition of acrylic acid. Azobisisobutyronitrile and ammonium persulfate were used as initiator and N,N-methylenebisacrylamide was used as the crosslinking agent. The characterization of the hydrogels was performed by thermogravimetric analysis, differential scanning calorimetry, infrared spectroscopy and swelling properties. The results obtained demonstrate different degrees of crosslinking and swelling of up to 490 ± 30%. The different properties of the hydrogels suggest different applications.

“…18, the film with the highest zeolite content has almost the same Young's modulus of elasticity with the pure PVA film, while the films with lower zeolite contents have lower elasticity which might be related to the high degree of crystallinity of the films [67]. The changes in the mechanical properties might be due to decreased crosslinking of the polymer chains and polymer chain length in the presence of the zeolite particles [68].…”

In the present study, potential application of the local clinoptilolite-rich natural zeolite in formulation of antibacterial hydrogels was investigated. The zeolite powder exchanged with cobalt(II) ions was used in preparation of the zeolite/poly(vinyl alcohol) hydrogel films in different amounts. The films were physically crosslinked by the freezing-thawing method and characterized for their crystallinity, surface and cross sectional morphology, chemical composition, thermal behaviour, mechanical properties, swelling and dissolution behaviours, and antibacterial activities against a Gram-negative bacteria. The films with 0.48 wt% and higher cobalt-exchanged zeolite contents showed antibacterial activity. Addition of the zeolite powder in the formulations did not cause significant changes in the other properties of the films.
