Polymer adsorption

Adsorption bụ nchikota nke ion ma ọ bụ ụmụ irighiri ihe n'elu akụkụ nke ọzọ. Mgbasa ozi nwere ike ime site na physisorption na chemisorption.Ions na ụmụ irighiri ihe nwere ike ịbanye n'ọtụtụ ụdị elu gụnyere elu polymer.A polymer bụ nnukwu molekul nke mejupụtara subunits ugboro ugboro jikọtara ọnụ site na covalent bond.Mgbasa ozi nke ion na molecules na elu polymer na-ekere òkè n'ọtụtụ ngwa gụnyere: biomedical, structural, na mkpuchi.
