A Study on the Adhesive Characteristics of Nano Scale Particles Considering Asperity Interaction
Chang-Hun Lee, Kyong-Hun Lee, Jun-Ho Yoon, Young-Eui Shin
Abstract
  In this paper, elastic and plastic adhesion index was very important in deciding adhesive characteristics and varying elastic and plastic index, dimensionless load and pull-off force were analyzed and simulated. Finally, using AFM, experimental surface roughness parameters of substrates and pull-off force between tip and substrates were produced. Using these values, pull-off forces were calculated and were compared with experimental pull-off forces. Through simulation and experiment, it was found that interaction of asperity also had very important influence on adhesive contact.
Key Words: Work of adhesion, Adhesin index, Interaction, Pull-off force, AFM
