Fig. 1: Formation, tribological, and mechanical enhancements of HNP-PDMS.

A Preparation process of the HNP-PDMS elastomer. B Molecular chain entanglement in the heterogeneous network structure. The borates ensure the stability of the phase separation; in the spherical phase, a small amount of the second network is entangled, whereas in the porous skeleton, a small amount of the first network is entangled. C Schematic of tribological and mechanical enhancements.
