“…Residual permeation of thin films of metals, metal oxides, or nitrides on polymers is attributed to “macro” and “nano” defects 39–42. In their permeation study of polymer barrier systems, Rossi and Nulman43 found that many small holes in a barrier layer lead to a much higher permeation than few large holes, of same total area.…”

International audienceIn a first part, this paper focuses on the interest of using a multilayer for vacuum insulation panels envelope. It is shown that piling up layers of metallized poly(ethylene terephthalate) does not seem to improve the initial barrier performance. In parallel, a permeation model to predict barrier properties of multilayer films was developed and validated with experimental results. In a second part, durability of a multilayer composite was investigated using accelerated hydrothermal ageing tests. It is shown that physical properties and in particular barrier properties decrease with ageing time. Polyurethane layer used as adhesive system in multilayer films is responsible for complete degradation of aluminum layer after 6 ageing months at 70 degrees C - 90% relative humidity.

Mechanical failure resulting from subcritical crack growth in the SiNx inorganic barrier layer applied on a flexible multilayer structure was studied by an electro-mechanical two-point bending method. A 10 nm conducting tin-doped indium oxide layer was sputtered as an electrical probe to monitor the subcritical crack growth in the 150 nm dielectric SiNx layer carried by a polyethylene naphthalate substrate. In the electro-mechanical two-point bending test, dynamic and static loads were applied to investigate the crack propagation in the barrier layer. As consequence of using two loading modes, the characteristic failure strain and failure time could be determined. The failure probability distribution of strain and lifetime under each loading condition was described by Weibull statistics. In this study, results from the tests in dynamic and static loading modes were linked by a power law description to determine the critical failure over a range of conditions. The fatigue parameter n from the power law reduces greatly from 70 to 31 upon correcting for internal strain. The testing method and analysis tool as described in the paper can be used to understand the limit of thin-film barriers in terms of their mechanical properties.
