This study was designed to investigate functionality of tetracycline‐loaded chitosan‐halloysite nanocomposite films, with focus on evaluating the influence of chitosan molar mass on films applicability for sustained local antibiotic delivery. The films were prepared by casting and solvent evaporation using low, medium, and high molar mass chitosan. SEM analysis revealed compact, nonporous and rough surface of the nanocomposite films due to the presence of halloysite agglomerates and tetracycline crystals. Increasing chitosan molar mass led to higher values of elongation at break (from 21.65 ± 2.65 to 34.48 ± 2.34%), tensile strength (from 134.8 ± 13.21 to 246.36 ± 14.69 MPa), and elastic modulus (from 633.79 ± 128.37 to 716.55 ± 60.76 MPa) of the nanocomposite films. FT‐IR, XRPD, and thermal analyses confirmed molar mass dependent chitosan‐halloysite interactions and improved thermal stability of the nanocomposite films in comparison with chitosan films. The nanocomposite films release...d tetracycline in a sustained manner, with the slowest release achieved from the films consisting of low molar mass chitosan. Chitosan molar mass was confirmed to be a functionality‐related characteristic of chitosan‐halloysite nanocomposite films as potential sustained‐release carriers for topical delivery of antibiotics.
