41. Crystal structure and crystallinity of poly(aryl ether biphenyl ether ketone ketone). Liu TX, Mo ZS, Wang SG, Zhang HF, Na H, Wu ZW. MACROMOLECULAR RAPID COMMUNICATIONS 18 (1): 23-30 JAN 1997.
The crystal structure of poly(aryl ether biphenyl ether ketone ketone) (PEDEKK) was determined to comprise a two-chain orthorhombic unit cell with dimensions a 0.778 nm, b = 0.606 nm and c = 2.375 nm by using wide-angle X-ray diffraction (WAXD). According to the orthorhombic system, the 12 reflections of this polymer were indexed. The crystallite size increases with increasing the crystallization ...

5. Polymer nanocomposites using urchin-shaped carbon nanotube-silica hybrids as reinforcing fillers. Zhang WD*, Phang IY, Shen L, Chow SY, Liu TX*. MACROMOL. RAPID COMMUN. 25 (21): 1860-1864, 2004.
Carbon nanotubes (CNTs) have been grown on MCM-41 supported Fe nanoparticles and the as-prepared (no further purification) CNT-silica hybrid was directly incorporated into nylon-6 (PA6) by simple melt-compounding. The urchin-shaped CNT-silica hybrid filler was observed to be homogeneously dispersed throughout the matrix by scanning 1 electron and transmission electron microscopy. Compared with nea...

课题组关于超分子超支化聚合物可控结构转化的研究工作在Macromolecular Rapid Communications上发表
超分子聚合物虽然具有动态可逆特性，但由于非共价键作用的存在，其结构在一定程度上具有不可控性。因此，寻找超分子聚合物结构调控的新方法已成为其研究领域的重要课题。本文合成了两种不同结构的单体AB2和CD2，其中AB2由二级铵盐功能化的柱[5]芳烃构成，而CD2含有一个中性客体和两个苯并-21-冠7基团。AB2单体在氯仿溶液中能通过二级铵盐与柱[5]芳烃的主客体反应自组装成超分子超支化均聚物[AB2]n。在AB2体系中加...
