摘要
预先合成了二巯基聚醚(HS-P(EO/PO)-SH)和乙烯基硅油(PVMS-b-PDMS),并以二者为原料,苯偶酰双甲醚(DMPA)作为光引发剂,利用巯基-烯点击化学法成功合成了对重金属离子具有吸附能力的有机硅弹性体。采用红外光谱仪、核磁共振氢谱仪表征了该有机硅弹性体的结构,并研究了其热稳定性以及在溶液环境下对重金属离子的吸附性能。结果表明,该有机硅弹性体具有优异的热稳定性,且室温下其对镍离子具有较好的吸附能力,是一种性能优异的重金属离子吸附材料。
The polysiloxane elastomer,which could be used as heavy metal ion adsorption material,was successfully synthesized with HS-P(EO/PO)-SH and PVMS-b-PDMS as starting materials by thiol-ene click chemistry.The structure of the polysiloxane elastomer was characterized by FT-IR and 1H NMR.The thermodynamic properties of the polysiloxane elastomer and the adsorption of heavy metal ions in solution were studied.The results showed that the elastomer had excellent thermal stability,and had a good adsorption ability to nickel ions at room temperature.It could be used as a kind of heavy metal ion adsorption material with excellent properties.
