Mechanochemistry, deep eutectic solvents and dynamic cross-linking strategies are combined to achieve the one-step preparation of stalk plastics
Stalk is an important biomass resource and converting it directly into high value-added products is a major challenge. Herein, we have cleverly utilized three novel techniques, mechanochemistry, Deep eutectic solvents (DES), and dynamic cross-linking, to achieve one-step in-situ plasticization of virtually worthless corn stalk into reprocessable thermoset plastics. This preparation strategy has many advantages, such as cheap and easy availability of raw materials, no need for catalysts, no need for pretreatment of raw materials, and no need for separation and purification of products. The stalk plastics have good mechanical strength, thermal stability, plasticity and reprocessability. In addition, cellulose plastic was prepared as a control experiment for stalk plastic, and the constitutive relationship between the structure of various components in stalk and the performance of plastic was deeply investigated. This strategy of developing new plastics from agricultural and forestry waste in a simple and environmentally friendly way will open up a whole new avenue for the production of more competitive bio-based plastics.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
