In this paper, non-woven micron-nanofiber mats of PLLA were successfully preparedviaelectrospinning technique, and the mats were characterized by SEM, their degradation performance was studied too. The results indicated that PLLA fibers have Bead-string morphology and the surface morphology changed to porous after degradation.

Microencapsulated phase change materials were achieved by solvent evaporation in this article, using polymethylmethacrylate as capsule’s shell and inorganic salt CaCl2•6H2O as capsule’s core. the effects of emulsion concentration and different ratio of core and shell to the microencapsulated phase change materials were discussed. The phase change material were added to the interior wall paints and its properties were characterized. The results showed that its enthalpy content will be different with the microcapsules and different storage time.

a novel fibrous catalyst containing palladium nano-particles was produced via electrospinning technique. The fibrous catalyst was characterized by scanning electron microscopy and transmission electron microscopy respectively, the results showed that the diameter of fiber was about 200 nm and the palladium (Pd) particles were in the range of 30~40 nm. The catalyst was tested in hydrogenations of α-olefins, cyclohexene and nitrobenzol in ethanol at room temperature under 1 atmosphere hydrogen. The results showed that the titled catalyst had high activity in the hydrogenations of α-olefins, cyclohexene and nitrobenzol.

Chitosan grafting acrylic copolymer (CTS-g-AA) supported Nano palladium catalyst was obtained in this paper. Chitosan grafting acrylic copolymer (CTS-g-AA) was prepared firstly and palladium was supported on CTS-g-AA; then nano fibrous catalyst was gained via electrospinning technique. The title catalysts were characterized by TEM, SEM and IR, the diameter of nanofiber was about 70~200 nm, the size of metal particles were in a range of 10~40 nm, and palladium particles dispersed on nanofibers homogeneously. The catalyst was applied to catalyze α-octene hydrogenation in normal temperature and pressure. The results showed that the conversion of α-octene was 99%, and the yield of octane was 65% by double-metal catalyst.
