ionic bond

Then the molecular imprinted polyethyleneimine on the surface of silica gel was prepared using Cu~ 2+ as template ions and epichlorohydrin ( ECH) as crosslinking agent via coordination bond effects, and composite ionic imprinted material IIP-PEI/ SiO_2 was obtained.

以Cu2+为模板离子，以环氧氯丙烷为交联剂，通过配位键作用，对化学键合在硅胶表面的PEI大分子链进行了离子印迹，制备了复合型Cu2+印迹材料IIP-PEI/SiO2；

The problem of whether the effect between particles is destroyed or not is analyzed in this paper, when ionic crystals, molecular atomic crystals and metallic crystals are melting, boiling or dissolving in water. That is the problem whether the chemistry bond is broken or not.
