Crystallization behavior of poly(ϵ‐caprolactone)/graphite oxide composites

A series of poly(ϵ‐caprolactone) (PCL)/graphite oxide (GO) composites were synthesized through the ring‐opening polymerization of ϵ‐caprolactone with GO as an initiator. The crystallization behavior of the PCL–GO composites and the effects of the PCL–GO composites as nucleation agents on the crystallization behavior of PCL were also studied. The introduction of GO as PCL–GO composites shortened the crystallization half‐time for both the isothermal crystallization and nonisothermal crystallization of PCL, and this clearly indicated that GO in the PCL–GO composites had a great nucleating effect on the crystallization of pure PCL.
