Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy: A Tool to Determine Reinforcement of Carbon Black in Polylactic Acid Composites

CODEN: MPCACD

Abstract

Infrared spectroscopy helps in investigating the relationship existing between the structure of polymer composites and their structure-sensitive properties by determining molecular interactions. Neat polylactic acid and carbon black (0.5, 1.0, 1.5, 2.0, and 2.5 wt.%) filled polylactic acid composites were fabricated via dissolution dispersion solution casting. Composites filled with 2.5 wt.% of carbon black showed increased mechanical properties in tensile mode, in comparison to its neat and filled polylactic acid. Hence, an interest in analyzing the structure and property dependence via attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy for neat polylactic acid and carbon black filled composites was felt. Analyzing ATR-FTIR spectrographs for neat polylactic acid and filled polylactic acid composites confirms strong interactions with the addition of carbon black; these interactions are at a maximum for 2.5 wt.% of carbon black. Displacement (i.e., shift), percent transmittance, and area of absorption peak in infrared spectra, confirm the strength of molecular interaction in polylactic acid composites, and are corroborated with the numerical values of the mechanical properties in tensile mode.
