how_to_build_a_mastercurve_for_lces

Anonymous (anonymous@undisclosed.example.com) — 2018-05-18T15:02:36+00:00

To build a mastercurve for any polymer means performing multiple tests spanning a wide range of frequencies and temperatures from below the glass transition to as high as possible but below the melting point. There are two ways of doing that, either scan multiple frequencies at each temperature (generally the fastest) or scan multiple temperatures at each frequencies.

how_to_cure_lces

Anonymous (anonymous@undisclosed.example.com) — 2018-05-18T14:56:52+00:00

Step 1: Heat treatment to make sure that all the solvent is evaporated from the specimen. Whichever state you want the specimen in after curing, it is safer to perform the heat treatment before any curing. It also helps making sure that you are not curing a physically aged state after a long storage.

how_to_perform_a_tensile_test

Anonymous (anonymous@undisclosed.example.com) — 2018-05-18T15:03:41+00:00

As the dumbbell specimen of LCE goes through a polydomain monodomain transition, its gage length becomes monodomain while its ends remain in the polydomain (softer) state. As a consequence, the strain is not homogeneous anymore during the uniaxial stretching and the heads of the specimen rather than the gage length tend to stretch and accommodate the imposed strain.
