“…The authors substantiated the relevance of the studies, primarily by the fact that steel pipelines, which are widely used in the oil and gas industry, constantly require repair due to damage from natural mechanical influences and corrosion [83,84]. In recent years, the most promising materials for repair have become polymeric composites and, first of all, epoxy resins [85].…”

Epoxy resins are oligomers containing epoxy groups and capable of forming cross-linked polymers under the action of hardeners. Epoxy resins are used in the production of adhesives, plastics, glass and carbon plastics, pouring compounds and plastoconcrete. These materials are widely used in construction, mechanical engineering, aircraft and rocket construction, shipbuilding. To improve the performance of epoxy resins, their chemical or physical modification is used. The paper focuses on physical modification of carbon nanomaterials in order to improve the strength characteristics. Methods for modifying epoxy resins with graphite, carbon nanotubes and graphene are analyzed. It is shown that graphene is the most promising material improving the strength characteristics of epoxy resins.

“…Although scholars have prepared some inorganic grouting materials and organic polymer grouting materials with good plugging effects, these grouting materials have some insurmountable defects. For example, inorganic materials have poor rheology and groutability, and organic polymer materials have weak mechanical strength, poor durability, and expensive . Accordingly, according to the concepts mentioned above, we adopt the design idea and strategy of combining organic–inorganic and double network and synthesized an organic–inorganic hybrid double‐network gel with simple preparation and low cost.…”

Effectively improving the mechanical properties of the hydrogel can greatly broaden its application range. The design concept of forming a double-network structure by organic-inorganic hybridization can greatly enhance the mechanical properties of traditional hydrogels. Here, a series of organic-inorganic double-network (OIDN) polyacrylamide/(sulfoaluminate cement) (PAM/SAC) composite gels by solution polymerization were synthesized at room temperature. The OIDN composite gels not only retain the characteristics of water swelling but also exhibit excellent tensile properties (stress and strain are 12 MPa and 2500%, respectively) and compressive strength (stress and strain are 65 MPa and 80%, respectively). In the preparation process, a brittle inorganic network of hydrated sulfoaluminate (hydra-SAC) and a ductile network of polyacrylamide (PAM) were formed by the manner of interpenetrating. The phase composition and thermal stability of the OIDN composite gels were characterized and determined by FTIR, XRD, SEM, and TGA, respectively. The effect of SAC on swelling and mechanical performance of the OIDN composite gels was also investigated. The results show that the use of SAC hybrid hydrogels can effectively improve the mechanical strength, and the OIDN composite gels are expected to be a potential grouting and plugging functional material.
