Özet:

 

In order to investigate the interaction of graphene oxide   (GO) with different cellulose polymorphs (I and II), we synthesized   cellulose (I and II)/GO composites using the sonication method.   Interestingly, no new peaks were observed in the FT-IR pattern of the   cellulose (I and II)/GO composites, indicating that no chemical reactions   took place between GO and cellulose. The X-ray diffraction patterns of   cellulose I and II/GO composites were slightly different than those observed   for cellulose I and II, indicating that some physical interactions occurred   between the GO and cellulose. Unexpectedly the ddd-spacing values and the   diffraction plane at the high-angle side were most likely expanded in   cellulose I rather than in cellulose II by adding GO, confirming the highest   reactivity of GO toward cellulose I rather than cellulose II. Furthermore,   SEM images showed that the conformal coating of GO on cellulose I was larger   than that on cellulose II due to the strong adhesion between the GO and   cellulose I. Cellulose/GO showed antimicrobial properties, and GO was found   to be promising for textile antimicrobial finishing.
