“…We found that the injection of a PVA solution (5-10% w/w) into a rotating VFD tube containing borax solution (100 mM), using a 2 mm jet inlet, resulted in the creation of PVA hydrogel films, with their surface morphologies strongly dependent on the rotation speed of the VFD tube. Borax solution has been used in different studies as a crosslinking agent to induce hydrogen bonds, creating hydrogels for various biomedical applications [70,71]. As observed, depending on the rotation speed, PVA hydrogel films were fabricated with different surface morphologies including radial (1000 RPM) and parallel (5000 RPM) grooves, flowerlike patterns (4000 RPM), and filling with irregular (2000 RPM) and spherical (3000 RPM) shaped particles ( Figure 2).…”

In recent decades, microfluidic techniques have been extensively used to advance hydrogel design and control the architectural features on the micro- and nanoscale. The major challenges with the microfluidic approach are clogging and limited architectural features: notably, the creation of the sphere, core-shell, and fibers. Implementation of batch production is almost impossible with the relatively lengthy time of production, which is another disadvantage. This minireview aims to introduce a new microfluidic platform, a vortex fluidic device (VFD), for one-step fabrication of hydrogels with different architectural features and properties. The application of a VFD in the fabrication of physically crosslinked hydrogels with different surface morphologies, the creation of fluorescent hydrogels with excellent photostability and fluorescence properties, and tuning of the structure–property relationship in hydrogels are discussed. We conceive, on the basis of this minireview, that future studies will provide new opportunities to develop hydrogel nanocomposites with superior properties for different biomedical and engineering applications.

“…The fenugreek gum (FG)/B hydrogels were recently developed by Liu et al as a potential water-retaining agent in agriculture. [51] Properties of the hydrogel were highly dependent on the FG concentration. Both G' and G'' values were increased by increasing the FG concentration indicating more resilient character of FG at higher concentrations.…”

Self-healing polyol/borax hydrogels have found great applications in various areas; especially in sensors, flexible electronics and biomedical fields. In this review, fabrication and characteristics of various types of borax-based hydrogels are discussed. Mechanical properties and self-healing behaviors of these hydrogels are strongly affected by the types of polyol, ratio of polyol:borax, and concentration of each component. Incorporation of highly polar nanofillers (such as cellulose nanofibers) into hydrogels and fabrication of double-network structures have been employed as the promising strategies for improving the mechanical properties. Other additives have also been examined to generate nanocomposite hydrogels for a wide variety of uses; e. g. polyphenols for developing adhesives, conducting polymers, and hybrid structures based on carbon nanotubes and graphenes for electroconductivity, Ag and ZnO nanoparticles for antibacterial property, and quantum dots for fluorescence.

Development of Biodegradable Agar-Agar/Gelatin-Based Superabsorbent Hydrogel as an Efficient Moisture-Retaining Agent

et al. 2020

Downgrading in the yield of crop is due to the inadequate availability of water. The way out for this trouble is to construct synthetic resources dependent on natural polymers with great water absorption and preservation limits. The present study investigated the design of agar-agar (Agr) and gelatin (GE) copolymerized methyl acrylate (MA) and acrylic acid (AA) hydrogel (Agr/GE-co-MA/AA) as a soil conditioner for moisture maintenance in agriculture. Agr/GE-co-MA/AA hydrogel was prepared by utilizing microwave-assisted green synthesis following the most suitable reaction conditions to obtain a remarkable water swelling percentage. The fabricated Agr/GE-co-MA/AA hydrogel was investigated through field emission scanning electron microscopy (FESEM), fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The water holding capacity of the soil and sand was examined by mixing Agr/GE-co-MA/AA hydrogel with soil and sand. The result demonstrates that the water holding time extended from 10 to 30 days for soil and 6 to 10 days for sand by using Agr/GE-co-MA/AA hydrogel. This synthesized biodegradable, low-cost and non-toxic Agr/GE-co-MA/AA hydrogel shows novelty as soil water maintaining material for irrigation in agriculture.
