Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Biomaterials

Background:

  • Shape memory polyurethanes are advanced materials with applications in smart devices.
  • Nanocrystalline celluloses (CNCs) offer unique properties for material reinforcement.
  • Developing high-performance biocomposites is crucial for advanced functional materials.

Purpose of the Study:

  • To develop a polycaprolactone-based shape memory polyurethane biocomposite reinforced with CNCs.
  • To investigate the effect of in situ incorporated CNCs on the mechanical and shape memory properties.
  • To explore the potential of the developed biocomposite for biomedical applications.

Main Methods:

  • In situ one-pot synthesis of CNC-enabled polyurethane biocomposite.
  • Mechanical testing (tensile strength, modulus of elasticity, elongation at break).
  • Shape memory property evaluation and rheological characterization.

Main Results:

  • Incorporation of up to 10 wt% CNCs significantly enhanced tensile strength (0.2 to 7.2 MPa) and modulus of elasticity (3.5 to 139.3 MPa).
  • Improved shape memory capability and shape fixity were observed with CNC addition.
  • Intimate interfacial adhesion between CNCs and the polymer matrix was confirmed.

Conclusions:

  • The developed CNC-enabled polyurethane biocomposite exhibits superior mechanical strength and shape memory performance.
  • The synergistic effect of CNCs as a nucleating and reinforcing agent is key to the enhanced properties.
  • The biocomposite shows significant promise for applications in the biomedical sector.
