Development of anti-adhesive coatings by using low-energy electron beam techlology

 

Surface functionalization provides both materials with innovative and improved properties as well as custom-designed and selective functions. Technologies for surface treatment are manifold and introduce surficial characteristics according to the functional requirements such as antimicrobial, biocompatible or anti-fouling properties. Surface modification techniques are often used in the field of biomaterial research as starting point for the performance of new medical devices. Low-energy, non-thermal electron beam technology (e-beam) represents a multifunctional tool with a wide range of applications, which can be used specifically for the functionalization of surfaces. Applying e- beam technology, surfaces can be either sterilized gently, surface properties can be effectively modulated or materials can be gradually crosslinked. The electron beam process is particularly gentle on materials since the low acceleration voltage causes minor material heating. In low energy electron beam processes, material surfaces can be functionalized at accelerating voltages of up to 200kV. Through a targeted selection of process parameters, it is possible to produce surfaces with tailored properties.[1] Substances, such as polymers or natural substances, can be covalently immobilized on a material surface through the e-beam process (e-beam grafting). It is therefore possible to produce substances with antimicrobial, biocompatible or anti-fouling properties. Low-energy electron beam technology can be easily integrated into in-line processes to realize modification of large areas. By extending the range of polymers or even natural substances, e-beam grafting can be applied in many biomedical fields.
