| 1 | The Rheological Property and Foam Morphology of Linear Polypropylene and Long Chain Branching Polypropylene显示文摘The rheological behavior, thermal properties and foam morphology of linear polypropylene and long chain branching polypropylene prepared through UV irradiation reactive extrusion were studied by rheological test, melt index test, DSC and supercritical carbon dioxide foaming technology. Rheological test and melt index test confirmed that under UV irradiation and extrusion, adding photo-initiator and cross-linking agent could achieve the purpose of branching, thus improved the melt strength of polypropylene effectively. The DSC results revealed that with the introducing of long chain branching, the melting range of the polypropylene broadened and the crystallization temperature increased. Owing to the introduction of long chain branches, polypropylene exhibited higher melt strength and strain hardening behavior. Compared with linear polypropylene, the foam morphologies of long chain branching polypropylene were more uniform. | 黄锦涛 HE Guangjian 廖霞 HUANG Yajiang YANG Qi | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，4： | 3 |

| 7 | Improved photostability of Vitamin A palmitate originating from self-assembled supramolecular gels显示文摘Retinyl palmitate(RP) is a derivative of Vitamin A and widely applied as the active component in the fields of cosmetic and pharmaceutics.RP can easily lose its physiological activity under UV irradiation due to its photosensitivity.In this work,it was found that the activity of RP remained 75% after 80 min of UVA irradiation when RP was entrapped in supramolecular gels formed by self-assembly of sorbitol-based gelators.By contrast,the activity of RP in conventional hydroxyethyl cellulose gels only remained 10% under the same conditions.These results showed that the supramolecular gels exhibited a significant protective effect on the photostability of RP.UV spectra of RP in supramolecular gels and corresponding solutions showed no distinct differences,indicating no change of the physicochemical properties of RP.The images of field-emission scanning electron microscopy and fluorescent optical microscopy suggested that the protection by supramolecular gels on the photostability of RP may be attributed to the three-dimensional network structure formed by the self-assembly of the gelators,which reduced the molecular collisions and the degradation process of the photoactivated RP.The present results showed that this protection can be influenced by the structures and the concentration of gelators as well as by the solvent composition. | WANG Hong FANG Fang LI Xue FU Cheng YANG YaJiang | 2012 | Chinese Science Bulletin2012，57，33： | 1 |
