WebNov 20, 2016 · Nanofibers in the unmodified chitin were thicker and heterogeneous. The thicknesses varied widely from 10 to 100 nm. The average diameter was 45 ± 8 nm. The great difference in morphology indicates that the carboxylate group of the esterified chitin helped the mechanical disintegration.
WebJul 23, 2010 · Chitin nanofibers were obtained from fresh shells of black tiger prawn ( Penaeus monodon ). The prawn shells were first immersed in 50 wt% ethanol solution at 20 °C for 12 h to remove pigments. Then, calcium carbonates in the chitin sample were removed by immersing the sample in 3.6 wt% hydrochloric acid solution at 20 °C for 24 h. WebFeb 11, 2024 · The nanofibers’ uniformity and low thickness morphology enabled the maleated chitin naofibers to be homogenously dispersed in water and PVA polymer matrix. On the other hand, the unmodified chitin treated with the same cycles of grinder was converted into thicker and non-uniform fibers (Fig. 2 b).
