nanotubes (CNTs) form multifunctional hybrid systems where the complementarity between polar groups of CS and the electronic-mechanical properties of CNTs generate synergies applicable in water treatment, energy storage, and electronic devices. In the field of water treatment, the hierarchical nano-roughness of surfaces has been shown to enhance superhydrophilicity through the formation of hydrogen bonding networks. In the context of energy storage, CS functions as a polyelectrolyte matrix, while CNTs establish three-dimensional percolation networks, thereby enhancing conductivity and stability. In electronic devices, this synergy facilitates the implementation of programmable ionic arrays for resistive switching and artificial synaptic plasticity. The present review discusses the underlying physicochemical fundamentals.

These attributes facilitate the homogeneous dispersion of CNTs through electrostatic interactions and hydrogen bridging, thereby overcoming the critical challenge of agglomeration inherent to nanotubes[4]. At the interfacial level, CS modulates surface energy and optimizes charge transfer to CNTs. The full exploitation of the intrinsic properties of CNTs, including their high electrical conductivity (>10³ S/cm), mechanical stiffness (elastic modulus ~1 TPa), and thermal stability, is thus enabled[5].

1. INTRODUCTION The utilization of nanocomposites of CS and CNTs exemplifies a sophisticated paradigm in the design of hybrid materials[1]. This paradigm is characterized by the synergistic relationship between the molecular functionality of the biopolymer and the exceptional properties of carbonaceous nanofillers[2]. The result of this relationship is the generation of systems that possess multifunctional capabilities. Chitosan, a cationic polysaccharide derived from chitin, functions as a pivotal structural matrix due to its density of polar functional
