AI Technical Summary
Traditional lubricating materials are difficult to control and adjust in harsh environments, and have poor mechanical properties, making them difficult to recycle.
Using liquid crystal epoxy resin as the base material, shape memory liquid crystal epoxy resin containing transesterification dynamic covalent bonds is prepared through thiol-epoxy click reaction. The lubrication performance is regulated by the crystalline-amorphous transformation of the mesocrystalline unit, and the material is recycled through transesterification dynamic covalent bonds.
It achieves intelligent control of lubrication performance, requires no additional lubricant, has good mechanical properties and self-lubricating properties, and the material is recyclable and suitable for use in a wide temperature range.
