摘要:A simpler approach is developed to obtain recyclable self-healing polysiloxane networks based on the thiol-ene reaction and Diels-Alder (DA) reaction. Tetramethyltetravinylcyclotetrasiloxane (D-4(Vi)) was first modified with furan via a thiol-ene reaction, giving furan-functionalized cyclotetrasiloxane (D1). D1 then reacted with bismaleimide to form thermally dynamic reversible crosslinking linkages via a Diels-Alder (DA) reaction. Thus, crosslinked networks (CNs) were synthesized and their depolymerization through the retro-DA reactions was thoroughly studied. The kinetics of the DA reaction was studied by H-1-NMR spectroscopic analysis of the model compounds. Results indicated that the DA reaction performs better at 60 degrees C and follows second-order kinetics. The CNs show strong photoluminescence when irradiated by UV light and exhibited potential application in recyclable adhesives for glass.
