PROBLEM TO BE SOLVED: To provide an antifouling imparting method of a novel structure which is free from the problem of toxicity, can exhibit antifouling effect with less blending amounts, and can maintain antifouling effect for a long term.SOLUTION: This invention provides a method of imparting antifouling property to polymer, wherein natural radioactive substance powder, with non-magnetized or demagnetized ferromagnetic powder, is added to polymer such as a coating, they are mixed and dispersed to impart antifouling property to the general-purpose coating, the coating is applied to the bottom of a ship or the like to be cured, and then subjected to magnetization treatment. As natural radioactive substance powder, normally used is natural radioactive mineral powder comprising Th and/or U as a primary radionuclide.

    【課題】毒性の問題がなく、少ない配合量で防汚効果が発揮でき、防汚効果の長期間の維持が可能な、新規な構成の防汚付与方法の提供。【解決手段】塗料等の高分子材に未着磁乃至脱磁処理の強磁性体粉とともに天然放射性物質紛を添加し、混合分散させて防汚性を汎用塗料に付与し、該塗料を船底等に塗布して硬化させた後、着磁処理を行う高分子材の防汚性付与方法。天然放射性物質粉としては、通常、一次放射性核種であるTh及び/又はUを含有する天然放射性鉱物粉を使用する高分子材の防汚性付与方法。【選択図】なし
