摘要：环辛二烯与双环戊二烯通过开环易位聚合制得了聚(双环戊二烯-co-环辛二烯)共聚物。当环戊二烯与环辛
二烯的质量比为 1∶1 时，制得的弹性共聚物的力学性能接近于聚二甲基硅氧烷（PDMS），可通过模塑成型工
艺实现高精度的微尺寸结构成型。利用聚双环戊二烯半固化凝胶的反应特性，仅需升温至 80 ℃并恒温 20 min，
即可实现共聚物与聚双环戊二烯基底之间的稳定键合。聚(双环戊二烯-co-环辛二烯)微流控芯片加工全流程耗
时<1 h。此外，共聚物微流控芯片可通过类似于 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。

Abstract: Poly(dicyclopentadiene-co-cyclooctadiene) copolymers were prepared from ring opening
metathesis polymerization of dicyclopentadiene (DCPD) with cyclooctadiene (COD). The copolymer
obained with a mass ratio of DCPD to COD of 1∶1 showed similar elastomeric properties as
polydimethylsiloxane (PDMS) and excellent replication fidelity at microscale. Based on the polymerization
activity of semi-cured gel, the stable bonding between copolymer and PDCPD could be achieved via baking
at 80 ℃ for 20 min. And it took less than 1 h to finish the machining process of poly(dicyclopentadiene-
co-cyclooctadiene) microfluidic chip. Furthermore, the chip fabricated by the copolymer could be
connected in a simple, effective manner similar to that of PDMS. Monodispersed droplets were obtained
using copolymer microfluidic chip and the size of the microdroplets could be tuned via changing the flow
rate of continuous phase.
Key words: polydicyclopentadiene copolymers; cyclooctadiene; elastomers; microfluidic chips;
monodispersed droplets; functional materials
