ATR-FTIR Analysis on Aliphatic Hydrocarbon Bond(C-H)For­mation and Carboxyl Content during the Ageing of DC Air Plasma Treated Cotton Cellulose and Its Impact on Hydrophilicity

摘要

The surface of the cotton fabric was modified using a direct current(DC)air plasma treatment and hence enhances its hydrophilicity.The Box-Behnken approach(design expert software)was used to optimise the input process parameters.The sample prepared under optimized condition is subjected to ATR-FTIR and Field Emission Scanning Electron Microscopy(FESEM)studies in order to determine the changes in hydrogen bond energies(EH),Total Crystallinity Index(TCI),Hydrogen Bond Intensity(HBI),Lateral Order Index(LOI),functionalization,lattice parameters(a,b,c&β),degree of crystallinity(in%)and surface etching.The ageing of this sample has been studied by comparing the values of carboxyl content and AC-C/AC-O-C ratio calculated using data extracted from ATR-FTIR spectra of the sample recorded periodically for one month.
