(yfm223@sohu.com) Source title: Rengong Jingti Xuebao/Journal of Synthetic Crystals Abbreviated source title: Rengong Jingti Xuebao Volume: 41 Issue: 4 Issue date: August 2012 Publication year: 2012 Pages: 1097-1101 Language: Chinese ISSN: 1000985X CODEN: RJXUEN Document type: Journal article (JA) Publisher: Chinese Ceramic Society, Baiwanzhuang, Beijing, 100831, China Abstract: RNS-A/Chitosan nanomaterial was obtained by using chitosan and hydroxypropylation RNS-A by the chemical bond. The preparation mechanism of the nanomaterial was discussed. The nanomaterial was characterized by FTIR, TEM and TG. The settling property and adsorption of the nanomaterial were investigated. The results showed that the nanomaterial was prepared through electrophilic and nucleophilic substitution reaction; Some holes and gaps which distributed to surface and interior of the nanomaterial were formed. The temperature of degradation was promoted to 318¡ãC from 263¡ãC, and the settling rate was about two times of chitosan |
