| 1 | Focus on polymer chemistry papers in Science China Chemistry of the year 2010显示文摘The journal Science China Chemistry published 63 papers in polymer fields in 2010,leading to a percentage increase of 473%compared to the year 2008 and 70%to the year 2009,respectively(Figure 1).In this year,three polymer Special Topics were designed and published:Biomedical Polymer(Number 3)[1],Advances in Principles of Polymerization(Number 8)[2]and Highly | TIAN Ying ZHU XiaoWen CAO Yong | 2011 | Science China Chemistry2011，54，2： | 2 |
| 2 | 不同氧化剂氧化对乙二胺荧光性能的影响显示文摘采用3种不同氧化剂对乙二胺进行氧化,并首次提出采用过氧化氢做氧化剂,对氧化后乙二胺水溶液的荧光性质进行系统研究。结果表明,过氧化氢氧化效果最佳,得到产品荧光强度最高,在紫外灯下可以看到明亮的蓝色荧光。pH值等于6时,乙二胺水溶液的荧光强度最强,并且与pKa密切相关。过氧化氢和过硫酸铵氧化的乙二胺水溶液的荧光强度在较低浓度范围内呈线性关系。实验结果表明,氧化乙二胺和大分子含氮有机物具有相似的荧光中心。 | 王少飞 贾丹丹 刘纯 田宏燕 刘璐 任艳军 王东军 | 2012 | 河北科技师范学院学报2012，26，2： | 1 |
| 3 | Synthesis and shape memory behavior study of hyperbranched poly(urethane-tetrazole)显示文摘A novel hyperbranched poly(urethane-tetrazole)(HPUTZ) was synthesized via the 'A2+BB2' ' approach using hexadiisocyanate(HDI) and 3-(bis-(2-hydroxyethyl)) aminopropyltetrazole(HAPTZ).The molecular structure was characterized by FTIR and 1H NMR spectroscopy.The number average molecular weight was measured to be 1.05×104 g/mol with a polydispersity of 1.27 by GPC analysis.The HPUTZ was further cured by the semi-adduct(PEG-IPDI) from polyethylene glycol(PEG) reacting with isophorone diisocyanate(IPDI) to form the crosslinked HAPTZ-PU film in different ratio of HAPTZ to PEG-IPDI.The glass transition temperature of HAPTZ-PU increased from 44.9 to 56.4 ℃ as the HPUTZ content increased from 20% to 33% from the DSC analysis.The DMA results indicated that the HPUTZ-PU with 20% HPUTZ possessed the highest storage modulus and loss tangent.However,the storage modulus increased with the increasing of HPUTZ segment at higher temperature.The shape memory study showed that all the films presented the excellent shape memory function.Over 98% shape recovery could be obtained for the HAPTZ-PU with 20%-33% HAPTZ segment content within 60 s in the tension deformation test and within 40 s at 80 ℃ in the bend deformation test. | QIAO LiGen ASIF Anila SHI WenFang | 2011 | Science China Chemistry2011，54，9： | 1 |
