The packing of polymer molecules
Webb13 sep. 2024 · Contaminants are bulky, often in the form of groups. Existing polymer adsorbents mainly use small molecules as cross-linking agents or building units, and the formed polymer molecular chains are small, and the rigidity between molecular chains is strong. Therefore, polymers often have more micropores and specific surface areas. … WebbA melt or solution of long entangled polymer chains flows like honey — very viscous, and even “elastic”, for example snapping back when you cut a flowing stream with scissors. …
