摘要
The JKR test has been used to quantify adhesion hysteresis between PDMS model networks having different amount of dangling chains. The adhesion hysteresis G - W appears time dependent, and increases with the amount of dangling chains. In accordance with recent investigations of interactions between a brush and an elastomer, it is believed that this hysteresis comes from the progressive bridging of the interface by pendant chains present in the network.
