摘要：Polymer reaction and performance improvement are oneof the importantcontents in the field of polymer materials science and engineering,in which polymer catalytic hydrogenation is an important part of polymerreaction. We reviewed the research achievements on polymer hydrogenationover the past 70 years and studied the mechanism of the hydrogenationreaction from the aspects of performance changes before and afterpolymer hydrogenation, the catalyst preparation/structure-activityrelationship, and polymer hydrogenation kinetics. We pointed out thedifficulty in separation and unsatisfactory high-temperature adaptabilityof traditional homogeneous catalysts and first proposed four effectsaffecting traditional heterogeneous polymer hydrogenation: scale effect,conformation effect, viscosity effect, and adhesion effect. Basedon the structure-activity relationship of polymers, we putforward the application direction of hydrogenated polymers at present.We found that using a new kind of nanometal catalyst (Pd/CNTs@FN)as hydrogenation catalyst can effectively reduce or eliminate thenegative effects of these four effects on the polymer hydrogenationreaction, and it is easy to separate from the reaction system. Theaddition of CNTs can effectively increase the specific surface areaof the catalyst and strengthen the interaction between reactants andcatalyst. Subsequent research should focus on designing the multiscalestructure and improving low-temperature activity of the catalyst,reducing process cost, and using green and efficient separation methodsto eliminate adverse effects, create a green and efficient polymerreaction system, accelerate the industrialization of polymer hydrogenationprocess, and provide theoretical guidance for the research and developmentof new polymer materials.
