| 1 | Synthesis of Castor Oil-based Cationic Waterborne Polyurethane Emulsion and Its Application显示文摘Castor oil-based cationic waterborne polyurethane(CWPU)was synthesized by pre-polymer process using castor oil(CO),poly(adipic acid-1,4-succinate diol)(PBA),isophorone diisocyanate(IPDI),and N-methyldiethanolamine(MDEA).The influences of the content of CO and MDEA on comprehensive performance and finished fabric properties of cationic waterborne polyurethane was investigated,especially the antibacterial properties of finished fabric.The CWPU latex particle size and its distribution decrease as the content of CO increased from 0wt%to 16.8wt%,and increases afterwards.The CWPU films show much higher thermal stability than cationic waterborne polyurethane without CO.The surface of fabrics was characterized by scanning electron microscope(SEM).The finished fabric surface is much smoother.In addition,the finished fabric with CWPU emulsion has better antibacterial property against E.coli and S.aureus.When MDEA content is 8%,the antibacterial rates of the two kinds of bacteria are 77.3%and 82.2%,respectively. | 吕志 易英 ZHANG Chen LüKai FENG Hao ZHANG Yanfei | 2020 | Journal of Wuhan University of Technology(Materials Science)2020，35，4： | 2 |

| 3 | The research of propagation characteristic and formation of double half-Gaussian hollow beams显示文摘A new kind of hollow beams, double half-Gaussian hollow beams,was put forward. With the help of the Collins formula, the analytical equation of propagation and transformation of the hollow laser beams in free space was deduced. The simulation shows that the intensity exhibits the three-dimensional trap distribution in the near-field, while the double half-Gaussian hollow beams turn into solid laser beams when propagating a certain distance, which shows the characteristics of self-focus. The double half-Gaussian hollow beams were obtained by means of the dual-reflecting splitting optical system. The intensity of the vertical loop in different distances was tested, which shows that the analytical equation of propagation and transformation is in agreement with the result. | DONG Yuan ZHANG XiHe NING GuoBin JIN GuangYong LIANG Wei LüYanFei ZHANG Kai | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，6： | 1 |

| 12 | Ionic Conductivity of Nano-LaF_3 Bulk Material at Room Temperature显示文摘Nanocrystalline powder of LaF3 was synthesized by a method of direct precipitation from water solution. Particle size and shape of LaF3 nanocrystalline powder was analysed with TEM. Particles were mainly spherical with narrow particle size distribution (10~20 nm). The average particle size analysed with XRD is 16.7 nm. Nano-LaF3 bulk material was prepared by compacting the powder to 1 GPa at room temperature and a vacuum of 10 -4 Pa. The ionic conductivity of nano-LaF3 bulk material was studied with complex impedance spectra at room temperature. The ionic conductivity of nano-LaF3 bulk material (1×10 -5 S·cm -1 ) at room temperature is significantly increased compared to that of single crystal LaF3 (1×10 -6 S·cm -1 ). A special phenomenon was observed firstly time that the ionic conductivity increased gradually with multiple testing in result of relaxation. | Wu Daxiong Wu Xijun Lü Yanfei Wang Hui | 2006 | Journal of Rare Earths2006，24，2： | 0 |
