By means of co-wrapping spinning process, the processability and performance of co-wrapped yarns based on continuous filaments and thermoplastics in manufacturing textile preforms were investigated. The results indicated that the co-wrapped yarns were suitable for the even premix and could be used to form textile preforms for manufacturing textile structural composites. The hollow spindle twist and hollow spindle rotational speed were the two main factors that affected the fiber fraction and properties of co-wrapped yarns. The empirical model by response surface methodology was established to optimum combination of hollow spindle twist and hollow spindle rotational speed in order to produce uniform co-wrapped yarns and performs.

Influence of Molecular Weight of PEO on Performance of Quasi-solid-state Dye-sensitized Solar Cells

引用

Journal of Wuhan University of Technology(Materials Science) 2010年第2期25卷 218-222页

作者：沈小林 School of Materials Science & Engineering Xi’an Jiaotong University

Quasi-solid-state dye-sensitized solar cells （DSCs） were prepared using gel electrolyte gelated by poly（ethylene-oxide）（PEO） with different molecular weight. With the increase in PEO molecular weight, the short circuit current densities （Jsc） increase significantly, which is related to the increase in I - diffusion due to the increase in free volume of gel electrolyte. However, only a slight increase in open voltage （Voc） is observed, which is explained by the decrease in dark current arising from the reduction of triiodide （I3^-） by conduction band electrons.

Amphiphilic block copolymers of poly（5-benzyloxy trimethylene carbonate）（PBTMC） and poly（ethylene glycol）（PEG） were synthesized through enzymatic polymerization using immobilized porcine pancreas lipase （IPPL）. The obtained copolymers with different compositions were characterized by GPC and IH NMR. The copolymer composition was in agreement with the feed ratio. The molecular weight of the copolymers showed an increasing trend with the decrease of PEG contents.
