Abstract: A new strategy for fabricating polyethylene (PE) superhydrophobic surface by utilizing the feature of “morphology duplicating effect” of Ziegler-Natta catalyst was investigated. The Ziegler-Natta catalyst components (MgCl2 and TiCl4) were first intercalated in between the montmorillonite (MMT) gallery and then the PE/MMT nanocomposite was prepared via in situ Ziegler-Natta polymerization. The surface morphology of PE/MMT was highly rough with a petal-like microstructure. The film made from such nanocomposite has the superhydrophobic performance with a water contact angle of (152.2±0.8)° without any modification by the low surface free energy material.

Key words: superhydrophobicity, Ziegler-Natta catalyst, montmorillonite, duplication effect
