Preparation and Comprehensive Performance Test of Superhydrophobic Paper Mulch Films

Abstract

Paper mulch was treated with nano-zinc oxide and nano-silica dispersion by a brushing method, and its mechanical stability, hydrophobicity, impermeability, and wet strength were verified. The experiment shows that the mulch film after brushing has superhydrophobic properties, and it can also have better superhydrophobic properties and stability after being allowed to stand at room temperature for 240 h and drying under a vacuum of 0.03 MPa under negative pressure. The wet strength test after soaking for different times shows that the mechanical properties of the base paper are reduced more than that of the hydrophobic paper. It is concluded that the hydrophobic coating can improve the wet strength of the paper mulch. The experimental results show that the coating has the erosion durability and mechanical stability of the paper mulch, the wet strength can improve, and the paper mulch has stronger mechanical stability and stronger ability to adapt to complex environments.

Nanosized ZnO/SiO2-Based Amphiphobic Coatings for Stone Heritage Protection

“…The ZnO/SiO 2 nanocomposites are beginning to be applied later in the amphiphobic field. The results showed that the composite coating has excellent chemical stability and hydrophobic properties, and the preparation method is simple and effective. − All of these studies have a positive guiding significance for the progress of this experiment.…”

Recent Advances of Biodegradable Agricultural Mulches from Renewable Resources

“…Cellulose is the main component of the plant cell wall that can be obtained from wood, cotton, and other plants. Natural cellulose is highly crystalline due to its strong intermolecular hydrogen bonds originating from the hydroxyl groups in cellulose glucose units. , Li et al conducted a study where they prepared a paper-based mulch with exceptional performance . They achieved this by applying a brush-coating technique using dispersions of zinc oxide nanoparticles and silica nanoparticles on a fiber paper floor mulch, as shown in Figure a.…”

“…40,41 Li et al conducted a study where they prepared a paper-based mulch with exceptional performance. 42 They achieved this by applying a brush-coating technique using dispersions of zinc oxide nanoparticles and silica nanoparticles on a fiber paper floor mulch, as shown in Figure 2a. The hydrophobic coating effectively covered the paper fibers, leading to a 15% improvement in the mechanical properties of the paper-based mulch under humid conditions compared to the original paper.…”

Preparation of a Superhydrophobic Surface by a One-Step Powder Pressing Method with Liquid Silicone Rubber As the Carrier

“…Superhydrophobic surface refers to the surface where the contact angle between water droplets and solid materials is greater than 150°, and the rolling angle is less than 10° when solid materials are in contact with water droplets. − Superhydrophobic surfaces are widely used in industry, military, and daily life because of their excellent hydrophobicity. − An important application of superhydrophobic surfaces is self-cleaning, which can effectively improve the waterproof and antifouling ability of its surface when it is used on glass, clothing, and metal. Superhydrophobic materials can also be used in pipeline antiscaling, oil–water separation, drag reduction, antiskid, anticorrosion, and other applications.…”
