Abstract: |
Scanning election microscopy (SEM) preparation techniques for samples such as paper, pulp, powder (filler and auxiliaries) and film were introduced. The common problems in SEM experiment were also discussed. The authors suggested using carbon conductive adhesive tape, silver liquid conductive adhesive to enhance the conductivity of the sample surface. As for the sample of fiber cross-section, using ion beam cutting technology could effectively avoid sample deformation caused by mechanical cutting. Optimizing coating time and accelera-ting voltage could significantly avoid the imaging problems caused by charging effect, edge effect, and electron beam damage. |
