ABSTRACT
The role of w interaction in surface dynamic change is examined using two model samples, cellulose (highly hydrophilic but highly crystalline) and cellulose acetate (moderately hydrophilic but amorphous), by extending the same experimental procedure for F-tagged surface previously employed [7]. The surface configuration change may be considered to be minimal for polymer molecules in the crystalline phase. It is, therefore, interesting to examine whether the crystallinity or the extent of water/polymer interaction is the dominant factor in the change of surface configuration when the contacting phase is changed.
