Meanwhile, the peak ( 101) at which the ladder polymer was formed showed that the diffraction intensity became stronger as the temperature rised. 同时,还观察到了代表梯形聚合物形成的(101)峰,其衍射强度随温度升高而加强。
P  ̄+ ion implantation of ladder polymer BBL 梯形聚合物BBL的磷离子注入
As pyrolytic temperature raised PAN linear type structure is converted to a ladder polymer with large conjugated structure of naphthyridine rings, and crosslinked to form a network lamellar structure with aromatic six-membered rings like graphite. 随着热解温度的提高,PAN线型结构转变成具有萘啶环大共轭结构的梯形高聚物,继而生成相互交联而成的共轭碳的类石墨芳香族六角网状层面结构。
We chose two kinds of materials, one is ladder conjugated polymer BBL, the other is fused perylene diimides-fluorene with enlarged π conjugated system. 我们着眼于两类材料:其一为梯形共轭聚合物聚吡咙BBL;另一类则是共轭体系扩大的二花酰亚胺并芴分子。
The structure of the fiber still consists of linear segments and ladder polymer segments; but the former gradually reduces and the latter increases. 此时纤维仍由线形链段和梯形链段两部分组成,但前者逐渐减少,后者增多。
