Core-Shell Ag-TiO2@EVA Preparation and Its Application in Wood Anti-Fungal, Anti-Mold and Anti-Decay Research

Using silver-loaded nano-TiO2 (Ag-TiO2) and ethylene-vinyl acetate (EVA) emulsion as raw materials, a core-shell structured Ag-TiO2@EVA composite material was synthesized to impart antimicrobial, mold-proof, and decay-resistant properties to wood. The study investigated the composite material’s efficacy in controlling wood-staining fungi and molds, as well as its decay resistance and antifungal performance. The results showed that when the film thickness was between 0.12 to 0.15 mm with an Ag-TiO2 content of 20% or more, or when the film thickness was between 0.21 to 0.24 mm with an Ag-TiO2 content of 15% or more, the control efficacy against Botryodiplodia theobromae and Aspergillus niger reached 100%, and the decay resistance grade against Poria placenta was level I. For samples with 10% Ag-TiO2 content, the inhibition zone diameters against A. niger and B. theobromae were both greater than 10 mm, while samples with 15% and 20% Ag-TiO2 content exhibited inhibition zones larger than 20 mm, indicating strong antimicrobial effects.

Preparation The Rose-like hydrophobic surface of wood based materials by soft lithography

To prepare hydrophobic wood with rose-like hydrophobic surface and avoid moisture damage to wood. In this paper, With polyvinyl alcohol (PVA) as the elastic mold, the microstructure of the rose petals was replicated on the wood surfaces by soft lithography. The soft lithography technique was used to modify the wood sur-face, transferring over it a rose-like topography, based on a micro/nano hierarchical structure using fresh rose as the template. The surface of poplar coated with polystyrene was reconstructed twice using 1, 3, 5, 8 and 10% PVA as templates, respectively. The results show that the average contact angle of poplar surface coated with polystyrene is more than 130°, that of fresh rose surface is about 140°, and that of untreated wood is about 60°. Therefore, the wood surface with polystyrene has obtained a similar structure to that of rose surface and has a certain hydrophobicity. In addition, the microstructures observed by means of SEM, showing rough surface structures with micro-nanopapillate hills on wood surfaces. Water droplets could easily roll down on such wood surfaces, exhibiting super-hydrophobic and low adhesion properties. The successful fabrication of rose-like wood provided a new direction for researches on the super-hydrophobic of wood, which could effectively prevent the damage of moisture to wood.
