본문내용

Ⅰ. Object
- Make a spherulite in a simple way.
- Understand the principles of the polarization microscope and the growth of the spherulite.

Ⅱ. Introduction
When crystals occur in molten states, crystal nucleus are created and the polymer chains are regularly attached to these central nucleus, which eventually growth of the spherulite.

<중 략>

Ⅳ. Procedure
1. Slice the polymer pellets thinly.
2. Put a piece of polymer on a slide glass and melting at the hotplate. ( Tm + 20 )
