In this work. organobentonite/sodium polyacrylate (OBT/PAAS) humidity-control composite material was prepared using intercalation polymerization. The humidity-control performance of this composite material was tested by desiccator method. Its morphology and structure were investigated by X-ray diffraction and environmental scanning electronic microscopy. https://fitnessgravesyardes.shop/product-category/side-cover/
