Dataset on the superabsorbent hydrogel synthesis with SiO2 nanoparticle and role in water restoration capability of agriculture soil.

Synthetic polymer was exploited as water-superabsorbent hydrogel and helped to conserve water in the agricultural soil. The hydrogel polymers were synthesized the carboxymethyl cellulose (CMC) and starch in addition to SiO2 nanoparticles. Superabsorbent hydrogel polymer having 35% water retention ability was analyzed with three replicates. Hydrogel increased the water restoration capability of agricultural soil.

This data will also help in developing eco-friendly polymer to reduce the mulching film problems in agricultural practices.

This data represented the impact of nanoparticles on the synthesis of superabsorbent hydrogel polymer.

1. Data

The dataset of this article described the consequence of SiO2 nanoparticles in the synthesis of superabsorbent hydrogel polymer from the crosslinking in between carboxymethyl cellulose (CMC) and starch with aluminum sulfate. The Fig. 1 shows the polymer film formation and hydrogel, Fig. 2 shows the electrical conductivity property of polymer film, Fig. 3 shows the plant growth. Table 1 shows the water retention of hydrogel with differing concentration of aluminium sulfate and Table 2 shows the growth of the plant in the presence and absence of hydrogel polymer.

Experimental design, materials and methods:

Synthesis of hydrogel polymer was conducted with SiO2 nanoparticles and analyzed for water retention capacity. Carboxymethyl cellulose sodium salt (CMC) and starch soluble in addition to SiO2 (20 nm) nanoparticles (enhance the surface area) were used to synthesize superabsorbent polymer films and aluminum sulfate octadecahydrate was used to establish crosslink in between polymer composite [4], [5].The DC electrical conductivities of polymer samples were analyzed by using 4200-SCS Keithley, it is a modular uses for characterization of electrical properties of materials. Two metallic electrodes were then connected to samples using silver wires. The transient I–V measurements done at room temperature. I–V characteristics help to determine electrical conductivities polymer samples. The amount of water retention was calculated by the formula (Gs−Gi)/Gi, where Gs is the weight of hydrogel after water absorption and Gi is the original weight of the superabsorbent polymer. Superabsorbent polymer was mixed with agriculture soil and used for sowing seeds of Vigna mungo [1], [2], [3], [4], [5]. Three replicates were used for the investigation of plants growth and germination of seeds.
