This study dealt with the formation of film, which included naphthalene carried on the film of chitosan. Three types of films are performed: one as a coating, the second as a composite film, and the third as a submerged film with an additional 14% naphthalene. Glass transition temperature (Tg) was tested by differential scanning calorimeter (DSC). Thermodynamic energy calculations from the Tg variation were made, which were used to evaluate and determine the types of destructive or formative bonds and the energy accompanied (given or taken by the addition of material to the matrix, such as naphthalene to the chitosan film). From the results, which indicate that there is depression in the Tg of the chitosan due to the addition of 14% naphthalene because naphthalene acts as a plasticizer, it means that naphthalene with chitosan forms a more flexible film compared with the pure chitosan film. Fourier transform infrared (FTIR) showed the chemical structure of chitosan and chitosan with 14 wt% naphthalene for the pure chitosan, coating, composite, and submerged films according to band values, which shows significant similarity between pure, coating, composite, and submerged films.
