Effects of amylose/amylopectin starch on starch-based superabsorbent polymers prepared by -radiation 作者:Zhang, YN (Zhang, Ya-nan)[ 1,2 ] ; Xu, SA (Xu, Shi-ai)[ 1,2 ] STARCH-STARKE 卷: 69 期: 1-2 特刊: SI 文献号: UNSP 1500294 DOI: 10.1002/star.201500294 出版年: JAN 2017 查看期刊信息 摘要 Biodegradable superabsorbent polymers (SAPs) were synthesized in this study by graft copolymerization of acrylic acid onto amylose and amylopectin using N,N-methylenebisacrylamide as a cross-linker, initiated by an initiator (potassium persulfate) and -ray radiation, respectively. The structures of the resultant amylose-graft-poly(acrylic acid) (amylose-g-PAA) and amylopectin-graft-poly(acrylic acid) (amylopectin-g-PAA) SAPs were characterized by Fourier transform infrared (FTIR) spectroscopy, solid-state C-13 nuclear magnetic resonance (NMR) spectroscopy, and thermogravimetric analysis (TGA). The main purpose of this study is to investigate the effects of the two initiation modes and chain structures of starches on the grafting ratios (GR) and properties of these amylose-g-PAA and amylopectin-g-PAA SAPs. The results show that SAPs prepared by -radiation have higher water absorption and GR than SAPs prepared by the initiator. In addition, amylose-g-PAA SAPs have higher water absorption and GR than amylopectin-g-PAA SAPs. The optimum water absorption is 530g/g for amylose-g-PAA SAPs and 355g/g for amylopectin-g-PAA SAPs, respectively. It is concluded that -radiation is more time-saving, energy-saving, and efficient than the initiator. 关键词 作者关键词:-Radiation; Acrylic acid; Amylopectin; Amylose; Superabsorbent polymers KeyWords Plus:GRAFT-COPOLYMERIZATION; RHEOLOGICAL PROPERTIES; HYDROGEL; ACID); IRRADIATION; WATER; COMPOSITE; KINETICS; CHLORIDE; REMOVAL 作者信息 地址: [显示增强组织信息的名称] [ 1 ] Qinghai Univ, Chem Engn Coll, Xining 810016, Peoples R China [显示增强组织信息的名称] [ 2 ] East China Univ Sci & Technol, Sch Mat Sci & Engn, Minist Educ, Key Lab Ultrafine Mat,Shanghai Key Lab Adv Polyme, Shanghai, Peoples R China 电子邮件地址:saxu@ecust.edu.cn 基金资助致谢 基金资助机构 授权号 Fundamental Research Funds for the Central University WD1315012 Foundation from Qinghai Science and Technology Department 2014-HZ-817 查看基金资助信息 出版商 WILEY-V C H VERLAG GMBH, POSTFACH 101161, 69451 WEINHEIM, GERMANY 类别 / 分类 研究方向:Food Science & Technology Web of Science 类别:Food Science & Technology 文献信息 文献类型:Article 语种:English 入藏号: WOS:000392428600002 ISSN: 0038-9056 eISSN: 1521-379X 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: EI3YI Web of Science 核心合集中的 "引用的参考文献": 40 Web of Science 核心合集中的 "被引频次": 0 |
