2011 IEEE international Conference on Waste Recycling,Ecology and Environment(ICWREE 2011)

作者： Wenbin YANG 1 2 * Kai ZHANG 3 Jinghui FAN3 Juying WU3 Qiang YAN4 1State Key Laboratory Cultivation Base for Nonmetal Composite and Functional materials Southwest University of Science and Technology Mian yang china 2 School of materials Science and Engineering Southwest Universit y of Science and Technology Mian yang china 3 Institute of System Engineering china academy of Engineening physics Mian yang china 4 Southwest Institute of physics Chengdu china

A kind of straightforward method was developed to fabricate Ag dendrites with hierarchical structures in AgNO3/HF/Si system at room temperature . High quality Ag dendrites were produced on silicon substrate as the form of uniform solid film with a thickness of 3 mm . The X-ray diffraction analysis reveals that face-centre cubic Ag phases are dominant in the dendrites. The non-equilibrium potential and anisot ropic growth at different reaction times result in morphological evolution . As the reaction proceeds , the dendritic structure transforms into thermodynamically stable hexagonal structure . It is believed that the global diffusion-limited aggregation as well as the locally oriented attachment of Ag grains are responsible for the formation of Ag dendrites.

＜正＞Corn starches with different amylose/amylopectin ratios（80/20,50/50,23/77, 0/100） were extruded using A Haake parallel,co-rotating twin-screw extruder （Rheomex PTW 24/40p,（?） 30） with a slit die（slit width 150 mm） to produce starch film. Processing behaviors of different starches during extrusion were systematically evaluated as functions of processing conditions（moisture content,extrusion temperature,screw speed and feeding speed）.
