Grafting of styrene into pre-irradiated fluoropolymer films: Influence of base material and irradiation temperature

Radiation‐Induced Graft Copolymerization of Styrene into Tetrafluoroethylene‐Hexafluoropropylene‐Vinylidene Fluoride (THV) Terpolymer Films

“…The radiation‐induced degradation is concluded to be the dominant process under these conditions. The deterioration of the mechanical properties of THV terpolymers by irradiation at room temperature is less dramatic compared to perfluorinated polymers like FEP,21 PTFE and PFA 22. The elongation at break of FEP films decreased to less than half of the initial value after irradiation with a dose of 50 kGy 21.…”

“…The elongation at break of FEP films decreased to less than half of the initial value after irradiation with a dose of 50 kGy 21. The copolymer PFA showed a behaviour like FEP, and the elongation at break of the PTFE film went even down to 20% of the initial value 22. On the other hand, the mechanical properties of partially fluorinated ETFE were found to be less affected by pre‐irradiation with a dose of 50 kGy 22.…”

“…The copolymer PFA showed a behaviour like FEP, and the elongation at break of the PTFE film went even down to 20% of the initial value 22. On the other hand, the mechanical properties of partially fluorinated ETFE were found to be less affected by pre‐irradiation with a dose of 50 kGy 22. The reason is that ETFE undergoes cross‐linking when irradiation is performed 9.…”

“…This result is in contrast to those as found for FEP and PFA previously. For these copolymers the irradiation temperature has a beneficial influence on the mechanical properties 21, 22…”

Radiation Induced Grafting of Acrylate onto Waste Rubber: The Effect of Monomer Type

“…To date, there is a lot of research that has been done using radiation-induced grafting to modify the polymer properties such as Uwe Lappan et al [4] conducted high energy radiation grafting of styrene onto fluoropolymers films and Przybytniak et.al [5] investigated functionalization of polymer surface by radiation-induced grafting of acryclic acid onto polyethylene, polypropylene and polystyrene. In 2014, Nor Azwin Shukri et al [6] successfully grafted antimicrobial agent onto polyethylene film through radiationinduced graft copolymerization and grafted film showed a strong and stable antibacterial activity.…”
