研究目的
To develop an environmentally safe hydrophobic cotton surface using PDMS and different morphologies of ZnO nanostructures to improve hydrophobicity.
研究成果
ZnO particles with different morphologies were successfully synthesized and used to create hydrophobic cotton surfaces. The ZnO nanoflakes with PDMS coating achieved the highest water contact angle of 144.15°, demonstrating the influence of morphology on hydrophobicity. The study provides a foundation for further research into hydrophobic coatings for textiles.
研究不足
The study focused on the effect of ZnO morphology on hydrophobicity but did not explore the long-term durability or environmental stability of the coatings. Potential areas for optimization include the scalability of the coating process and the integration of other nanomaterials for enhanced properties.
1：Experimental Design and Method Selection:
The study involved synthesizing ZnO nanostructures (nanospheres, nanoflakes, nanorods) via sol-gel and solution-precipitation methods, followed by coating cotton with PDMS and ZnO nanostructures using a dip-coating method.
2：Sample Selection and Data Sources:
Cotton cloth was used as the substrate. Precursors for ZnO synthesis included zinc acetate dihydrate, zinc chloride, and zinc nitrate tetrahydrate.
