    Understanding the effect of nanoporosity on optimizing the performance of self-healing materials for anti-corrosion applications
    (IOP Publishing, 2011-01-01) Sellaiyan, S; Smith, SV; Hughes, AE; Miller, A; Jenkins, DR; Uedono, A
    The chromate-based epoxy primer film was prepared on glass and metal surfaces using various graded doctor blades. The quality and consistency of the films was assessed using scanning electron microscopy and the porosity within the film characterized by positron annihilation lifetime spectroscopy. The positron lifetime (τ) distribution for the epoxy polymer matrix was resolved using the CONTIN program. The free volume was found from the ortho-positronium component. The optimum thickness for the films was established for future structure/activity studies. © 2014 IOP Publishing LTD
