Abstract: The present disclosure relates to the technical field of protective coatings, and provides a graphene oxide (GO)-modified styrene-acrylic Pickering emulsion and a composite emulsion, and preparation methods and use. In the present disclosure, GO is added during polymerization of a styrene-acrylic monomer, and the GO is attached to an interface of a styrene-acrylic core while forming the styrene-acrylic core; and the GO is “stitched” at the interface of the styrene-acrylic core by a silane coupling agent, thus giving the GO a better dispersion effect. After adding a shell phase emulsion, a part of the styrene-acrylic core that is not completely wrapped by a GO sheet may be grafted with a shell phase, and cross-linking between a core phase and the shell phase can further enhance a steric stability of the GO; and the GO can fully connect the styrene-acrylic core with a siloxane shell, improving the molecular configuration of a siloxane component. In the composite emulsion, GO has desirable dispersibility and is not easy to agglomerate, such that the composite emulsion has an excellent performance and can significantly improve the durability of a cement-based material.

Abstract: A device and method for monitoring freezing-thawing damage of an underwater concrete member in situ. A main structure includes an upper link, concrete member, transverse sealed box, longitudinal sealed box, movable guide rod, probe launching box, multichannel data collector, frequency modulation transmitter, computer, auxiliary wheels, lower link, and a wireless temperature sensor. A process includes four steps: launching of a probe, collection of data, calculation of an elastic modulus, and evaluation of freezing-thawing damage. The device is simply structured, easy to operate, and can be reused, and provides power for launching the probe by non-contact force transmission by using high-strength magnets of the same pole, resolving the sealing problem, and calculates the elastic modulus of the concrete member by using acceleration data obtained by a probe, so as to obtain a loss amount of the elastic modulus, thereby performing real-time in-situ monitoring for freezing-thawing damage of an underwater concrete member.
