Crystallization Behavior of Poly(ε-caprolactone) in Spin-coating Film-forming processes

ORAL

Abstract


Crystallization behavior in spin-coating film-forming processes has been investigated for Poly(e-caprolactone) (PCL) having the weight-average molecular weight (Mw) of 129×103, 39×103 and 16.8×103 by time-resolved measurements of grazing-incidence small-angle and wide-angle X-ray scattering (GISWAXS) using synchrotron radiation in SPring-8 (RIKEN, Japan). Effect on the rotational speed, the PCL concentration in solutions and the molecular weight of PCL on crystallization kinetics and lamellar orientation during spin-coating will be explained in my presentation.

*This research was partly supported by JSPS KAKENHI Grant Number 26410135 and CREST, JST. The synchrotron radiation experiments were performed at BL45XU in SPring-8 with the approval of RIKEN (Proposal No. 20140061, 20150076, 20160041, 20170094).
