دانشمندان ماده سفید درخشانی را بدون قطره رنگدانه سفید ایجاد کردند

Scientists create brilliant white material without a drop of white pigment

Researchers have created a foam-based material that produces intense whiteness and water repellency without titanium dioxide pigments or PFAS chemicals. Inspired by natural structures in snow, clouds, flowers, and lotus leaves, the material uses tiny pores to scatter light while its rough surface repels water. The technology could offer a more sustainable way to make white, water-resistant everyday materials.
