| Abstract: |
| N-halamines,a new class of biocides,overcome some of the disadvantages caused by the traditional biocides in practical applications.They are environmentally friendly germicides due to their fast and efficient sterilization,storage stability,and regeneration.Earlier studies on N-halamines mainly focused on the syntheses and applications of small molecular organic N-halamines such as five membered and six-membered heterocyclic N-halamine compounds.Compared to traditional inorganic halogen-containing disinfectants such as chlorine gas,sodium hypochlorite,chlorine dioxide,these heterocyclic N-halamines can maintain disinfection capacity in the water for longer time due to their better stability.Since the late 20th century,non-leaching biocial N-halamine materials have received much attention.Some novel N-halmine precursors with binding groups have been covalently bounded to various materials such as cellulose fiber,silica gel,polystyrene,polyethylene,and polyurethane to produce non leaching biocidal materials.Specially,the successful development of macroporous cross-linked N-halamine polymer resin materials (Halopure) and related technologies created a new era for the applications of N-halamine materials in the disinfection of drinking water.In this review paper,the antibacterial mechanism and synthetic methods of N-halamine biocidal materials and their application prospects in various fields of daily life were introduced.Their development prospects were also made. |
