Investigation of free volume in polymer blend systems by positron annihilation lifetime spectroscopy and dielectric relaxation

Conference Simon, G P ; Zipper, M D ; Hill, A J

Polymer blends form an important area of current technological and academic interest. Due to macromolecular size, entropy of mixing is low and thus full polymer miscibility (mixing on a molecular scale) is rare and many blends are often immiscible. The presence of specific interactions between polymers can, however, lead to partial or full miscibility. Generally, techniques such as microscopy, light scattering and glass transition measurement are used to assess the degree of miscibility. This work presents the results obtained from two characterisation techniques, Positron Annihilation Lifetime Spectroscopy (PALS) and dielectric relaxation spectroscopy (DRS). PALS is a matter/anti-matter technique in whichmore »« less

Temperature dependence of positron-annihilation lifetime, free volume, conductivity, ionic mobility, and number of charge carriers in a polymer electrolyte polyethylene oxide complexed with NH{sub 4}ClO{sub 4}

Journal Article Haldar, B ; Singru, R M ; Maurya, K K ; ... - Physical Review, B: Condensed Matter

Various physical properties of the solution-cast films of the proton conducting polymer polyethylene oxide (PEO) complexed with ammonium perchlorate (NH{sub 4}ClO{sub 4}) have been studied in the temperature range 300{endash}370 K. These properties studied by us include free volume by positron lifetime spectroscopy, ionic conductivity by impedance spectroscopy, ionic mobility by transient ionic current technique, number of charge carriers, dielectric constant, etc. The hole volume and conductivity show a steep rise at {ital T}{approx_equal}{ital T}{sub {ital m}} ({approximately}333 K). It appears that the increase in free volume arises out of the increase in the size of the holes rather thanmore »« less

The states of water within poly(vinyl alcohol) thin films part 1: Investigations by positron annihilation lifetime spectroscopy

Conference Hodge, R M ; Edward, G H ; Simon, G P ; ...

In order to produce poly(vinyl alcohol) (PVA) material suitable for thermoplastic processing, it is necessary to plasticize the polymer with water. In the present study the accommodation of water within the PVA network is examined. Positron annihilation lifetime spectroscopy (PALS) is used to determine the effect of water on the free volume of the polymer. The PALS parameters give information on the average size of the free volume sites and the relative concentration of free volume sites. A model is proposed in which water initially enters the polymer in a molecular form, distributing itself along and becoming bound to themore »« less
Characterization of fatigue-induced free volume changes in a bulk metallic glass using positron annihilation spectroscopy

Journal Article Vallery, R S ; Liu, M ; Gidley, D W ; ... - Applied Physics Letters

Depth-profiled Doppler broadening spectroscopy of positron annihilation on the cyclic fatigue-induced fracture surfaces of three amorphous Zr{sub 44}Ti{sub 11}Ni{sub 10}Cu{sub 10}Be{sub 25} metallic glass specimens reveals the presence of a 30-50 nm layer of increased free volume that is generated by the propagating fatigue crack tip. The presence and character of this fatigue transformation zone is independent of the initial amount of bulk free volume, which was varied by structural relaxation via annealing, and the voids generated in the zone by intense cyclic deformation are distinct from those typical of the bulk.
