Marine material and manufacturing method thereof

The present invention is capable of preventing marine pollution after use while maintaining the original functions of marine materials when used in a state of being immersed in seawater or fresh water and when stored/stored in air before use. The marine material, which is used in a state in which at least a portion of the marine material is immersed in seawater or fresh water, is a resin containing polylactic acid (PLA) and poly (butylene adipate/terephthalate) (PBAT). The present invention suppresses hydrolysis of the constituent elements when used in a state in which at least a portion of the constituent elements are immersed in seawater or fresh water, and when the constituent elements are stored/stored in the air before use, and promotes hydrolysis when implanted in the seabed or the river bottom after use. 能够在以没入海水、淡水中的状态来使用时、以及使用前的空气中保管/库存时维持海洋材料的本来的功能，并且防止使用后的海洋污染。通过将以至少一部分没入海水中或淡水中的状态来使用的海洋材料的构成要素设为含有聚乳酸(PLA)和聚己二酸对苯二甲酸丁二醇酯(PBAT)的树脂，以构成要素的至少一部分没入海水中、淡水中的状态来使用时、以及使用前在空气中处于保管/库存状态时，构成要素的水解得到抑制，另一方面使用后着床于
