Table 1. Soaking Experiment Resultsa.
T | θinit | θsoak | θsta | Ff-max |
---|---|---|---|---|
20 | 121.1 ± 0.01 | 116.1 ± 0.05 | 113.3 ± 0.23 | 2.91 ± 0.13 |
25 | 121.0 ± 0.01 | 117.2 ± 0.03 | 113.9 ± 0.10 | 3.36 ± 0.06 |
30 | 121.2 ± 0.20 | 117.7 ± 0.08 | 114.5 ± 0.09 | 3.18 ± 0.05 |
The effective solid energy change after soaking γla·(cos θsoak – cos θinit) 5.58 mN/m for 20 °C is comparable with the immersion energy 6 mN/m of Teflon measured by Chessick et al.14.
