摘要：

将两种具有不同结构的共轭高分子聚糠醇鄄苯酚(PFP-0)及聚对苯撑(PPP-0)分别在一定条件下热活化处理后, 成功地用作为染料废水处理催化剂PFP及PPP; 利用DTA-TG、TEM、FT-IR、UV-Vis等技术对样品进行了表征. 结果表明, PFP及PPP在自然光照射及空气氧存在的温和条件下, 很短时间内就能使染料亚甲基蓝(MB)几乎完全脱色降解和大部分矿化; 材料共轭结构对其稳定性能有较大的影响; 横向比较分析发现, 极性基团的存在, 对材料的催化性能有重要影响.

Abstract:

After properly heat-activating the polymers poly(furancarbinol-co-phenol) (PFP-0) and polyparaphenylene (PPP-0), two new functional polymer nanomaterials, PFP and PPP were obtained. Their properties as catalysts in water pollution treatment were studied. The samples were determined by means of DTA-TG, TEM, FT-IR, and UV-Vis. The results showed that under natural light and air conditions, dye methylene blue (MB) could be almost fully degraded and largely mineralized on them within a few minutes; the variation of the conjugation structure had great influence on their stabilities; compared with each other, the existence of polar groups was found to be decisive factor to the catalytic properties.
