“…Those structures combining the favourable properties of each polymeric component of the semi-IPNs or IPNs have attracted considerable interest. Their potentials lead to new systems with properties that are superior to those consisting of single components [ 202 ]. A linear polymer, such as alginate, agarose, and carrageenans, physically gets through another crosslinked network, but they do not covalently bond with each other.…”

Hydrogels are three-dimensional crosslinked hydrophilic polymer networks with great potential in drug delivery, tissue engineering, wound dressing, agrochemicals application, food packaging, and cosmetics. However, conventional synthetic polymer hydrogels may be hazardous and have poor biocompatibility and biodegradability. Algal polysaccharides are abundant natural products with biocompatible and biodegradable properties. Polysaccharides and their derivatives also possess unique features such as physicochemical properties, hydrophilicity, mechanical strength, and tunable functionality. As such, algal polysaccharides have been widely exploited as building blocks in the fabrication of polysaccharide-based hydrogels through physical and/or chemical crosslinking. In this review, we discuss the extraction and characterization of polysaccharides derived from algae. This review focuses on recent advances in synthesis and applications of algal polysaccharides-based hydrogels. Additionally, we discuss the techno-economic analyses of chitosan and acrylic acid-based hydrogels, drawing attention to the importance of such analyses for hydrogels. Finally, the future prospects of algal polysaccharides-based hydrogels are outlined.

Waterborne styrene/acrylate latex interpenetrating polymer network (LIPN) with core‐shell structure was synthesized via a three‐stage emulsion polymerization method. A natural montmorillonite (MMt) and an organically modified montmorillonite (OMMt) were used to see their effect on the morphology and damping properties of polymer‐clay nanocomposite LIPN. The samples were characterized by dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), dynamic mechanical thermal analysis (DMTA), and X‐ray diffraction (XRD). The appearance of a single peak in the particle size distribution curve and nearly monodisperse latex particles observed in the SEM images indicated that all LIPN particles were of nanoscale size, without evidence for new nucleation occurrence. TEM images demonstrated that latex particles had clearly core‐shell structures. It also showed that most of the OMMt clay platelets were encapsulated in the polymer latex particles. According to the tan δ‐temperature curve, addition of 0.5 wt% OMMt to the core layer improved the damping properties of the LIPN, while MMt could not affect the damping curve significantly. The results indicated that the diffusion of polymer chains into the OMMt clay galleries has increased the internal friction and so improved the damping properties.

Novel polyacrylamide‐based hydrogels containing 3‐(trimethoxysilyl)propyl methacrylate and/or tetraethoxy silane were synthesized by means of frontal polymerization, using ammonium persulfate as initiator, N,N′‐methylene bisacrylamide as crosslinking agent and dimethyl sulfoxide as solvent. The obtained samples were treated at pH of 2 or 5 to induce the sol–gel reaction and evaluate their swelling behavior in the conditions. The occurrence of this reaction was assessed by solid‐state NMR. Moreover, the thermal properties of the dry materials were studied by differential scanning calorimetry and thermal gravimetric analysis, and their water‐contact angles were measured. It was found that the amount of Si affects the extent of swelling and the hydrophilicity of the resulting materials. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
