Malvern Instruments Discusses GPC/SEC Analysis of Polymer Solutions Used in Inkjet Printing

Published 02 February 2017 | By Malvern Panalytical

Inkjet printing of polymer solutions is an area of interest for depositing precise, high-throughput patterns of functional polymer. The applications of the polymer patterns include OLEDs, organic circuits, and textiles. The efficacy of this printed pattern can be negatively impacted by the concentration and viscosity of the polymer solution, the molecular weight and molecular weight distribution of the polymer, and level of branching in the polymer. Therefore, it is of keen interest to understand the effect of inkjet printing on the degradation of polymers. In this application note, the molecular weight (MW) and molecular weight distribution (MWD) of various polymers is shown as a function of time during inkjet printing. The data shown in this application note is from references [1-2].
