Cellulose nanocrystals (CNCs) have attracted considerable attention as nanofillers to enhance the crystallization of poly(lactic acid) (PLA) and to improve the mechanical properties of the composites. There are two challenges: the inferior thermostability of CNCs and the compatibility of CNCs and polymeric matrix. Poly(ethylene glycol) epoxide, a compatibilizer and carrier, was grafted on CNC surfaces...
In order to improve the thermal stability of cellulose nanocrystals (CNCs) and to weaken their hydrophilicity, extensive research has been conducted to graft hydrophobic molecular chains on CNC surfaces to cover and/or replace hydroxyl and sulfate ester groups. According to our previous research, it was proposed that triazine derivative is an ideal candidate to modify CNCs. In this study, triazine...
This work investigates reinforcing poly(lactic acid) (PLA) nanocomposites using triazine derivative-grafted cellulose nanocrystals (CNCs). A hydrophobic triazine derivative was synthesized and applied to modify CNCs to improve their thermal stability and diminish the hydrophilicity of the nanoparticles. CNCs before and after modification were used to reinforce PLA nanocomposites by a hot compression...
Polyimides exhibit outstanding thermal and thermo‐oxidative stability, excellent solvent resistance, good mechanical and electrical properties and superior chemical resistance. However, their practical applications are frequently limited by their infusible and insoluble nature. Structural modifications of the polymer backbone have been utilized to modify polyimide properties, either by reducing the...
