title: Preparation of the superhydrophobic nano-hybrid membrane containing carbon nanotube based on chitosan and its antibacterial activity.
abstract: The functional nano-hybrid surface containing multi-walled carbon nanotubes (MWCNT) on chitosan incorporated with the cationic chitosan (C-CS), MWCNTs and silicon couple agent (KH-560) was designed and prepared. The nano-hybrid membranes (NHM) containing MWCNTs were modified by perfluorooctanesulfonyl fluoride (PFOSF). The superhydrophobic multi-functional membranes with biological activity and superhydrophobic surface were obtained. The incorporated MWCNTs improved the roughness of the nano-hybrid membranes. The perfluorinated end groups of the nano-hybrid membrane surface provided low energy surface. The antibacterial activity, surface superhydrophobicity and mechanical property of the perfluorinated nano-hybrid membranes (PFNM) were discussed. Their morphological structures and surface ingredients were characterized by energy dispersive X-ray spectrometer (SEM-EDX). The PFNMs had excellent antibacterial property and superhydrophobicity. The novel nano-hybrid membranes with excellent antibacterial, superhydrophbic, and mechanical properties have potential applications in the food engineering, bioengineering fields and medical materials.
