Abstract: Under the New Engineering Education framework, there is an urgent need for light chemical engineering discipline to bridge the gap between fundamental theories and industrial practice. This study addresses the disconnect between petroleum-based teaching materials in polymer chemistry and physics courses and the biomass-focused modern industry. We propose an instructional reform centered on the “three major plant components”, establishing a “disassembly-structure-property-characterization” pedagogical framework. This approach transforms pulping and papermaking phenomena into scientific explorations of polymer chain structures, aggregated states, and material viscoelasticity. The modular design emphasizes comparative analysis, integrating classical polymer theory with the unique physicochemical properties of plant components. Innovative experiments like “nanocellulose disassembly” enhance students' ability to address complex engineering problems at molecular levels and foster interdisciplinary integration. Results demonstrate that this model effectively improves students' academic competence and innovation capabilities, while supporting biomass valorization and the green transformation of light industries, aligning perfectly with New Engineering Education's goals for cultivating interdisciplinary engineering talent.
