Research progress in ageing effect of surface modification by low temperature plasma

Low temperature plasma,as a novel surface modification technology,is characterized by clean,high efficiency and energy-saving.Plasma treatment can improve the surface properties of polymer materials without affecting their bulk features,which impart itself a potentially abroad application in the field of surface modification.However,the plasma-improved surface properties usually decay with time,known as ageing effect of plasma treatment.The mechanism and characterization methods of ageing effect as well as approaches to overcome ageing effect were briefly reviewed.The influences of polymer structure,plasma treatment parameters,such as gas,treating time and power,and storage environment on ageing behavior were especially discussed.
