Preparation of Urushiol-Titanium Chelate Polymer/Multiwall Carbon Nanotubes Composite Honeycomb Films With Chemical Resistance by Breath Figures

摘要

Urushiol-titanium chelate polymer (UTP), the reaction product of urushiol with titanium compound, has been used as a heavy anti-corrosive coating in chemical industries in China. UTP could not be made into regular honeycomb-porous film just using breath figures, whereas that could be done with the incorporation of hydroxylated multiwall carbon nanotubes (MWCNT). MWCNT showed significant influences on the formation of highly ordered microporous films. The preparation conditions also affected the honeycomb structure of films and then exhibited different morphologies. The results measured from energy dispersive X-ray spectra showed that the content of oxygen around the hole of UTP/MWCNT microporous film was higher than that on the wall of the hole. Moreover, UTP/MWCNT microporous film had excellent acid, alkali, and organic solvent resistance properties. (C) 2014 Society of Plastics Engineers
