Materials | Free Full-Text | Synthesis and Characterization of Novel

Novel carbon nanofiller-based starch-g-polyacrylamide hybrid flocculation materials (St-PAM-CS) were in situ prepared using potato starch (St), acrylamide (AM), and hollow mesoporous carbon spheres (CSs; diameters of 300¨C400 nm).

Synthesis of starch-g-p(DMDAAC) using HRP initiation and the

The major factors affecting the properties of starch-g-p(DMDAAC) are the degradation degree of the starch, DMDAAC content, and HRP content, as discussed below. Conclusions. Starch-g-p(DMDAAC) was synthesized by graft copolymerization of 25 g of degradation starch and 25 g of DMDAAC using HRP (12 mg)/H 2 O 2 (15 mL) initiation at 45 ¡ãC for 6 h.

Synthesis and application of amphoteric starch graft polymer

1. Introduction Starch is a naturally abundant polysaccharide and a low cost material. Many chemical modifications of starch have been carried out for its use, such as etherification, esterification, oxidization, cross-linking and graft copolymerization through hydroxyl groups.

The Thermal Gelation Behavior and Performance Evaluation of High

The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by varying NPAM or PEI concentration, and a quadratic model is developed by statistical analysis, which predicts the gelation time of NPAM/PEI gel system.
