The present invention relates to an average-density-adjustable structure and more specifically provides a structure the average density of which is adjusted by changing the material of the structure and the size of a void formed therein and which can thereby float on the surface of or in a liquid and can easily bond with or change a material present in a gas or liquid by being equipped with a first material, which is one among an organic catalyst, an inorganic catalyst, a microorganism, and a biomolecule.
本发明涉及一种可调节平均密度的结构,更具体地说,它提供了一种结构,通过改变结构的材料和其中形成的空隙的大小,可调节其平均密度,从而可漂浮在液体表面或液体中,并通过配备第一种材料(有机催化剂、无机催化剂、微
生物和
生物大分子中的一种),可轻松地与气体或液体中存在的材料结合或改变其密度。
