  • Effects of Electron Beam Irradiation on Shear Strength of Laminated Sheet of Bio-Adaptable Polydimethylsiloxane (PDMS) and Polytetrafluoroethylene (PTFE) with Fracture Toughness
    MATERIALS TRANSACTIONS, 2015
    Co-Authors: Chisato Kubo, Arata Yagi, Masae Kanda, Yoshitake Nishi
    Abstract:

    Effects of homogeneous low voltage electron beam irradiation (HLEBI) without glue on the adhesive Force of tensile shear strength (¸B) at each shear probability (Ps) of laminated PDMS/PTFE sheets of polydimethylsiloxane (PDMS) and Polytetrafluoroethylene (PTFE) were investigated. AlthoughB of shear at low and mid Ps of 0.06 and 0.50 were 0.015 and 0.04MPa before treatment, 0.22MGy-HLEBI enhanced theB up to the largest values of 0.098 and 0.11MPa of the laminated sheets, respectively. They were more than 6 and 3 times larger than those before treatment. On the other hand, additional HLEBI apparently reduced theB of laminated sheets irradiated at more than 0.43MGy as usual radiation damages. The effects of HLEBI on adhesion Force ofB can be explained by the enhancement of cross-linking at PDMS/PTFE interface. When HLEBI cut the chemical bonds and generated active terminated atoms with dangling bonds at cross-linked PDMS and PTFE polymers, strengthening the bonding Force of cross-linking polymers was induced by the chemical bonding and Intermolecular Attractive Force.

  • effects of electron beam irradiation on adhesive Force of laminated sheet of high strength polytetrafluoroethylene ptfe and bio adaptable polydimethylsiloxane pdms

    Abstract:

    The effects of homogeneous low voltage electron beam irradiation (HLEBI) on the adhesive Force of peeling ( o Fp) and peeling resistance energy ( o Ep) at each peeling probability (Pp) of laminated sheets of bio-adaptable polydimethylsiloxane (PDMS) with transparency and high strength polytetrafluoroethylene (PTFE) with sterilization were investigated without glue. Although both o Fp and o Ep of peeling at low Pp of 0.06 were 0.2N·m ¹1 and 4.0 © 10 ¹2 J·m ¹1 before treatment, HLEBI enhanced the o Fp and o Ep up to the largest values of 11N·m ¹1 and 2.2J·m ¹1 of the laminated sheets irradiated at 0.13MGy, respectively. They were more than 55 times larger that those before treatment. On the other hand, additional HLEBI reduced the o Fp and o Ep of laminated sheets irradiated at more than 0.22 to 0.86MGy, although they were apparently larger than those before treatment. In order to investigate the influence of EB irradiation on o Fp and o Ep, electron spin resonance (ESR) signals related to dangling bonds were observed. When HLEBI cut the chemical bonds and generated dangling bonds with nonbonding electrons in PTFE and PDMS, the electrons induced the chemical bonding and Intermolecular Attractive Force. HLEBI induced strong adhesive Force of laminated sheets was explained by the discussion. Therefore, it was concluded that HLEBI was a useful tool for quick lamination of bio-adaptable PDMS and high strength PTFE. [doi:10.2320/matertrans.M2012124]
