Preparation method of organic-inorganic hybrid super hydrophobic modified bacterial cellulose aerogel oil absorption material

Abstract

A preparation method of an organic-inorganic hybrid super hydrophobic modified bacterial cellulose aerogel oil absorption material relates to a preparation method of an oil absorption material. The invention aims to provide the preparation method of the organic-inorganic hybrid super hydrophobic modified bacterial cellulose aerogel oil absorption material. The bacterial cellulose aerogel is subjected to organic-inorganic hybrid super hydrophobic modification to obtain the super hydrophobic aerogel oil absorption material. The method comprises the steps as follows: 1, bacterial cellulose cultivation; 2, bacterial cellulose aerogel preparation; and 3, preparation of the organic-inorganic hybrid super hydrophobic modified bacterial cellulose aerogel. The oil absorption material prepared by the invention has good selective oil absorption performance, can be conveniently used for oil-water separation or absorption of the oil spill in the water, has no pollution to the water body, and is a novel oil absorption material with great application potential.

Description

technical field

[0001] The invention relates to a preparation method of an oil-absorbing material, in particular to a preparation method of an organic-inorganic hybrid superhydrophobic modified bacterial cellulose airgel oil-absorbing material. Background technique

[0002] In recent years, with the increasing development of offshore oil resources, oil spill accidents have been increasing. Similar oil spills happen every year in the world. With the acceleration of industrial society, my country's oil pollution is becoming more and more severe. On May 5, 2010, the crude oil spill in the Gulf of Mexico in the United States attracted great attention from the international community. An oil drilling platform on the coast of Louisiana in the southern United States caught fire and exploded at around 10 pm local time on April 20, 2010, causing 7 serious injuries. , At least 11 people are missing. The nearly three-month oil spill not only caused huge economic losses, but also broug...
