Application
- Oil absorption enhancement with hydrophobic nanofibrils: Hydrophobic cellulose nanofibrils modified with Diphenylmethane 4,4′-diisocyanate and other diisocyanates demonstrated improved performance in absorbing circulating oil, offering significant potential for environmental cleanup applications (Chen et al., 2024).
- Evaluation of adhesion enhancers for foliar applications: Research on self-assembling eugenol-loaded particles, which might involve Diphenylmethane 4,4′-diisocyanate for carrier adhesion on leaves, indicated enhanced efficiency in foliar applications and underscored the importance of ecotoxicological safety (Zhang et al., 2023).
- Development of deformative polyurethane actuators: Diphenylmethane 4,4′-diisocyanate was used in the synthesis of self-healing polyurethane actuators that respond to light, heat, and humidity, highlighting its utility in creating smart materials for advanced engineering applications (Dong et al., 2023).
