Determination of Hemp Crystallinity by Different Evaluation Method

Abstract:

This paper used X-ray diffraction, infrared spectroscopy and nuclear magnetic resonance (NMR) to determine the crystallinity of hemp fiber. The results show that the order of crystallinity is Segal method > Peak deconvolution method > Newman method > Infrared spectroscopy method. Both empirical formula and peak deconvolution method lead to deviation of crystallinity value. However, there is a less inaccuracy in peak deconvolution than empirical formula and could get detailed crystal parameters. Therefore, peak deconvolution method is more suitable than empirical formula for determination of crystallinity of hemp fiber.
