摘要: This manuscript studies the relation between macroscopic properties of soy protein isolate (SPI)-based superabsorbent polymers (SAP) (e.g., water uptake capacity and tensile properties) extent chemical modification conducted on protein. The increase in carboxyl group content, obtained from electrometric titrations, for acylated systems compared to native SPI brings with it an improvement hydrophilic character, as revealed by determination imbibing capacity. SEM images show that larger porous regions were developed plastics. As their mechanical properties, static measurements indicated plastics greater values display higher extensibility, reference sample. These natural-based SAP materials could be appropriate applications which maintaining dimensional stability during service is not crucial (e.g. agriculture horticulture).
