This invention belongs to the field of oil and gas field development technology and discloses a temperature-pH dual-responsive smart fracturing proppant and its preparation method. The proppant adopts a three-layer core-shell structure, including a high-strength ceramic or quartz sand core, a polyvinyl alcohol crosslinking transition layer reinforced with nano-silica, and a poly(N-isopropylacrylamide-co-acrylic acid) copolymer smart response layer.
