Effects of Guar Gum and Sodium Benzoate on the Properties and Hydrophilicity of Silk Fibroin Hydrogels

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 425 - 425

Silk fibroin (SF)-based hydrogels were prepared by the simple evaporation method. The outcomes of SF-based assessed for consideration in terms practical and convenient use. Guar gum (GG) sodium benzoate (SB) are blending reagents to SF solution poured into petri dish make hydrogels. After leaving mixture three days solidify, all peeled off characterized. SF-blend guar (SF-GG) SF-GG-blend (SF-GG-SB) could be constructed, but different textures levels transparency. SB affected solid texture resulted a higher water contact angle (WCA) value hydrogel than SF-GG. results from Fourier transform infrared spectroscopy (FTIR) indicated main functional groups substances that contained Moreover, some interactions between also detected. A thermogravimetric analyzer (TGA) was used determine decomposition as function temperature. DTG thermograms, which exhibit maximum temperature, revealed interaction forces SF, well their structure, reason thermal stability SF-GG-SB have tensile strength SF-GG In conclusion, appearance, texture, hydrophilicity, stability, types concentrations substances. This suggests properties designed adjusted attain desirable fitting target applications.
