WebDimethyl Biphenyl. A biphenyl molecule is composed of two benzene rings fused together. In the most common form of biphenyl, each benzene ring is bonded to a methyl group. Dimethyl biphenyl is a clear, colorless liquid with a sweet, floral odor. It is used as a solvent and in the production of plastics, resins, and other chemicals. WebIn this work, a shape memory epoxy resin based on the orientable biphenyl mesogen and the dynamic siloxane is fabricated successfully via anion ring-opening polymerization. The resulting epoxy resin exhibits excellent shape memory performance, good reprocessing ability, good self-healing property, and triple shape memory effect (triple-SME).
