Odor Absorption Performance of Cotton Fabrics Functionalized with Beta-Cyclodextrin

Abstract Cyclodextrins are cyclic oligosaccharides known for their ability to form inclusion complexes with various molecules due to their distinctive chemical structure. This characteristic enables cyclodextrins to alter guest molecules’ chemical and physical properties, rendering them useful across numerous applications. Volatile aromatic amines such as aniline are common environmental contaminants and can constitute a significant fraction of measured aromatic amines in indoor and industrial contexts. This study focuses on the capacity of β -cyclodextrin ( β -CD) to adsorb unpleasant odors by forming inclusion complexes with volatile organic compounds. Cotton fabric treated with β -CD was subjected to vapors of aniline and cyclohexylamine substances notorious for their pungent odors. A range of characterization techniques was utilized, including Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Time of Flight-Secondary Ion Mass Spectrometry (ToF–SIMS), and Gas Chromatography–Mass Spectrometry (GC–MS), to evaluate the formation and stability of the inclusion complexes.
