摘要 力平衡实验与 Johnson-Kendall-Roberts (JKR) 理论相结合已被用来确定固体系统之间的粘附功。事实证明，对变形行为的理解不足可能会导致错误的结果。为了解决这些缺陷，引入了一种修改程序，用于通过力平衡实验和 JKR 理论使用正常位移行为来确定粘附功。该程序涉及改进的实验和数据分析方案，并已应用于为 PDMS 聚（二甲基硅氧烷）-PDMS、PDMS-F（氟化硅）和 PDMS-Si（硅）系统提供更精确的粘附值。粘附力测定的工作量始终小于通过接触角测量估计的工作量。
Abstract Force-balance experiments in conjunction with the Johnson-Kendall-Roberts (JKR) theory have been used to determine the work of adhesion between solid systems. It has been shown that deficiencies in understanding the deformation behavior can lead to erroneous results. A modified procedure for determining the work of adhesion by force-balance experiments and JKR theory using normal displacement behavior has been introduced to address these deficiencies. This procedure involves improved experiental and data analysis protocols and has been applied to give more precise work of adhesion values for PDMS poly(dimethylsiloxane)-PDMS, PDMS-F(fluorinated silicon) and PDMS-Si (silicon) systems. The work of adhesion determinations are consistently less than those estimated by contact angle measurements.
