Warning: My computer died and the new computer with Windows eight does not
support Microscoft Front Page. I am in the process of switching to
Microsoft Expression Web but this will take some time . This will mean a
new website and hopefully an improved website. (RDC 7/6/2015)
This site is now, up and running. It will take a while before the search
engines find the site. Just click on the link below.
From now on all new additions will be on the plasticspatents site. Gradually all
the content from this site, maropolymeronline, will be transferred to this new
site. (RDC 7/17/2015)
The Maro Patentpedia is a dynamic ever-growing collection of US
Patent titles, abstracts and notes on Polymer Science and Technology. This
includes background notes from different sources. Topic pages are added as new developments appear,
resulting in a dynamic, up-to-date encyclopedia.
Because Applications are so important, a special
Application section is being developed. (6/19/205) Visit
Applications under development. A special
Application Alerts service is being considered.

Direct conversion of
solar energy to electrical energy can provide a virtually unlimited source of
clean energy. Conventional photovoltaic modules typically include a stack of
materials encapsulated in a transparent polymer such as ethylene vinyl acetate
(EVA) copolymers. During lamination, EVA is applied to a photovoltaic module
and cured to prevent long term creep due to temperature and stress. Crosslinking
is critical to long term performance and must be monitored. Conventional
crosslinking measurements are the “gel fraction” test and "creep" test
requiring destruction of the tested material. An automated, nondestructive test
is badly needed.
Dobble et al measured
cross-linking by localized deformation without damage to the module. A polymer
sample is indented and the relaxation or a recovery recorded. This recovery is
then compared to a reference material. An
automated test for crosslinking could be a major step in quality control as well
as monitoring long term performance.
US Patent 8,950,267 (February 10, 2015), “ Methods and Apparatus for Detecting
Cross-Linking in a Polymer,” Dan
Doble, Rafal Mickiewicz, John Lloyd, Marco Jaeger, and William F. Hartman (Fraunhofer
USA, Inc., Plymouth, Michigan, USA).
