Cationized reduced GO-cellulose/polyamide fabric and properties

What is it about?

In this work, the cellulose/polyamide fabric was cationized with 3‐chloro‐2‐hydroxy propyl trimethyl ammonium chloride to attract more graphene oxide (GO). The fabric was then treated with GO followed by reduction with sodium dithionite.

Why is it important?

Energy‐dispersive X‐ray spectroscopy, X‐ray diffraction, X‐ray photoelectron spectroscopy, UV reflectance (100%), the color change of fabrics, the electrical resistance (0.6 × 103 Ω sq−1) and washing fastness indicated entire coverage and well stability of rGO on the fabric surface of the fabric surface. The antibacterial activities of the treated fabrics improved against Gram‐negative bacteria including Escherichia coli (84.8%) and Pseudomonas aeruginosa (96.4%) and also Gram‐positive bacteria consisting Staphylococcus aureus (100%) and Enterococcus faecalis (98.4%). Finally heating of the cationized rGO fabric at 220 °C displayed a lower electrical resistance (0.5 × 103 Ω sq−1) so the thermogravimetric analysis showed that heating has a slight effect on the dimensional thermal stability of the treated fabric as shrunk (2.43%).
