a, Schematic diagram of the solid–solid sliding performance test device. The specific measurement procedures and sample details are described in Methods. b, Friction coefficient variations of solid PCM (tetradecanol as the sample) on the LLS and unmodified surface. The applied load is 10 N and the cyclic motion length is 50 mm. c, Front-view photograph of the rheometer (Anton Paar MCR 103) used to test the torque of liquid PCM (tetradecanol as the sample) on the LLS and unmodified surface. d, Schematic diagram of the test platform including CP50 cone plate and surfaces to be tested. e, Torque (s.d. n = 3) variations of liquid PCM (tetradecanol as the sample) on the LLS and unmodified surface with different shear rates, under a testing temperature of 47 °C.
