Background:

  • Chitosan (CHI) is a biocompatible polymer with diverse applications.
  • Poly(aminopropylsiloxane) (pAPS) offers unique siloxane properties.
  • Hybrid materials combine properties of different components for enhanced functionality.

Purpose of the Study:

  • To synthesize and characterize novel chitosan/poly(aminopropylsiloxane) hybrid films.
  • To investigate the structural and thermal properties of these hybrid materials.
  • To explore the effect of lithium ion incorporation on the hybrid film structure.

Main Methods:

  • Sol-gel method for pAPS oligomer synthesis.
  • Blending CHI with pAPS to form hybrid films.
  • Characterization using SEM, XRD, FT-IR, and thermal analysis.

Main Results:

  • Formation of chitosan/pAPS nanocomposite films with organized microscopic patterns.
  • Evidence of systematic interactions between chitosan and pAPS components.
  • Lithium perchlorate incorporation altered the hybrid film structure, inducing anisotropic patterns above a critical concentration.

Conclusions:

  • Chitosan/pAPS hybrid films represent a new class of nanocomposites.
  • The structure and properties of these hybrids are tunable.
  • Lithium ion concentration is a critical factor influencing the morphology of CHI/pAPS hybrid films.
