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 (M_w) 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.
