| 摘 要： | 本文报道了聚(双环戊二烯-co-环辛二烯)微流控芯片的制备方法。引入环辛二烯作为共聚单体,与双环戊二烯通过开环易位聚合制备得到弹性共聚物。当环戊二烯与环辛烯的质量比是1 : 1时,制得共聚物的力学性能接近于聚二甲基硅氧烷(PDMS),弹性共聚物具有较高的微尺寸结构成型精度。利用聚双环戊二烯半固化凝胶的反应特性,实现共聚物与聚双环戊二烯基底之间的稳定键合。共聚物微流控芯片可以通过类似于PDMS的连接方式,实现简单、高效的密封连接。利用共聚物微流控芯片制得单分散的微液滴,控制连续相的流速即可实现微液滴尺寸的调变。关键词：聚双环戊二烯共聚物；环辛烯；弹性体；微流控芯片；单分散液滴；中图分类号：TQ630 文献标识码： A 文章编号：1003-5214 (2020) 01-0000-00

| Abstract: | This paper reported the preparation of poly(dicyclopentadiene-co-cyclooctadiene) microfluidic chips. Elastomer PDCPD copolymer was synthesized by ring opening metathesis polymerization of dicyclopentadiene (DCPD) with cyclooctadiene (COD) which was introduced as comonomer. when the mass ration of DCPD: COD was 1 : 1, as-synthesized copolymer showed the similar elastomeric properties as PDMS and excellent fidelity of replication at microscale. We achieved persistent bonding between copolymer and PDCPD based on the polymerization activity of semi-cured gel. Chips fabricated by copolymer can be connected in a simple, effective manner which similar to that of PDMS chips. Monodispersed droplets were obtained using copolymer microfluidic chips and the size of the microdroplets can be tuned via changing the flow rate of continue phase. |
