| titleOfInvention | Preparation method of super-hydrophilic super-oleophylic loofah sponge |
| abstract | The invention discloses a preparation method of a super-hydrophilic super-oleophylic loofah sponge, which comprises the steps of removing seeds and skins of loofah sponge, then carrying out vacuum drying to completely dehydrate the loofah sponge, then grinding the loofah sponge into powder, sequentially removing lignin by using hydrogen peroxide and hemicellulose by using alkali to obtain pure biological cellulose, then mixing the biological cellulose with water to carry out mechanical pulping, and carrying out vacuum freeze drying, condensation, crystallization and sublimation of water on the obtained slurry to enable the slurry to have rich microporous structures, thereby obtaining the loofah sponge with super-hydrophilic super-oleophylic characteristics. The invention has the advantages of easily obtained raw materials, lower cost and simple operation, the whole process is completed under the conditions of no pollution and no emission, and the prepared loofah sponge has excellent super-hydrophilicity and super-lipophilicity and has wide application prospect in the fields of adsorption, impurity removal, filtration or shock absorption, noise elimination and the like. |
