Patent ID: 8309226

Claim:
A method for preparing an article comprising a transparent substrate and an electrically conductive transparent coating, comprising the steps of: reacting carbon nanotubes with a halogenated precursor comprising a halogen and a halogenated compound to obtain a halogenated intermediate comprising filled and/or coated carbon nanotubes, wherein the halogenated compound is selected from the group consisting of MgI 2 , ScI 3 , ScBr 3 , YI 3 , TiI 4 , VI 3 , VBr 3 , MoI 3 , MnI 2 , FeI 2 , CoI 2 , NiI 2 , PdI 2 , PtI 2 , BI 3 , PbI 2 , BiI 3 , and any combination thereof, depositing the halogenated intermediate on a transparent substrate to form an electrically conductive transparent coating on the substrate, removing halogen contents partially or completely from the halogenated intermediate, whereby the article is prepared.
