The principal aim of this research study is to discuss the influences and effects of the acetylation degree of chitosan on antibacterial properties, mechanism, and thermal properties. Various chitosan with different degrees of deacetylation (DD%) were dissolved in acetic acid solution to produce films. The basic structure of chitosan consists of different ratios of amine (-NH2) and acetic (R-HNCO-R). The discussion in this research paper also includes bacteriostasis, sterilization antibacterial capabilities, thermal manufacturing properties, and mechanisms.
