Abstract:The present invention provides a preparation method of superhydrophobic styrenic thermoplastic elastomer materials. Plastic SEBS is used as the substrate; good solvent/poor solvent induced phase separation of SEBS is adopted, combined with the introduction of low-surface-energy palm wax and annealing treatment to fabricate superhydrophobic SEBS surfaces. The superhydrophobic surface constructed by virtue of low surface energy and rough structure achieves outstanding hydrophobicity, thereby resisting the adsorption of butylphthalide dissolved in aqueous solutions for anti-butylphthalide adsorption applications.The good solvent/poor solvent induced phase separation method requires no expensive equipment and features simple processes and convenient production. The constructed superhydrophobic SEBS surface takes full advantage of both the surface rough structure and the low-surface-energy property of palm wax, delivering superior anti-butylphthalide performance. The invention also provides the superhydrophobic styrenic thermoplastic elastomer material, infusion medical devices and corresponding applications.
