摘要
用四种掺杂剂,I_2、Br_2、BF_3·乙醚和发烟H_2SO_4,作了聚苯乙炔(PPA)的掺杂。对掺杂及未掺杂的PPA做了电导率测定。实验表明,发烟H_2SO_4掺杂效果较好(电导率提高10~7倍),I_2较差。对不同分子量和不同密度的PPA的电导率测定表明;PPA分子量越高,电导率越高;PPA密度越大,电导率越高,并且PPA分子量越大,掺杂后电导率提高的幅度也越大。本文还讨论了掺杂机理和无水AlCl_3在苯乙炔聚合过程中的同步掺杂作用。
The four Kinds of dopants, I2, Br2, BF3. ether and fuming H2SO4, are used in doping of polyphenylacetylene. It is discovered that the effect of fuming H2SO4 is the best and of I2 is the west. The conductivity of polyphenylacetylene and doped polyphenylacetylene is measured. The conductivity of polyphenylacetylene of various molecular weight and density is measured also and these experiments state that the higher the molecular weight is, the higher the conductivity is, and the larger the density is, the higher the conductivity is.
