+    "protocol": "The hydrophilic nano-SiO2/PVA coating was fabricated by the solution blending method and deposited on PE film using a dip coating technique. The addition of nano-SiO2 into PVA was aimed at improving the network structure, mechanical properties, thermal stability, and water resistance of the film.1. Prepare a PVA solution at 5 wt% in water. 2. Mix the PVA solution with Ludox (N2010, SS3010) via mechanical stirring for 1 hour. 3. Dilute the resulting solution with deionized water. 4. Add fluorocarbon surfactant at a concentration of one thousandth to the diluted solution to reduce surface tension. 5. Immerse the PE film in the hybrid solution for 5 seconds. 6. Perform thermal treatment of the PE film at 80°C for 5 minutes to evaporate the solvent."
