US 12,595,361 B2 · Transferable composition and methods for preparing and using the same

Abstract

There is disclosed a transferable composition being applicable to a membrane serving to transfer a pattern of the composition to an intended substrate. The transferable composition comprises a swellable polymer swelled by a swelling agent and particles dispersed therein. Methods of preparing the composition, applying it to a transfer membrane as a pattern, and transferring the pattern to a substrate, as well as articles made thereby, are also provided. The transferred patterns may serve a decorative and/or functional purpose and the transferable compositions may accordingly include decorative and/or functional particles. When the functional particles are or can be rendered electrically conductive, a pattern formed therewith can be part of a conductive circuit and can serve, for example, for the manufacturing of a solar cell.

Dependent claims

A method for preparing a transferable conductive composition, the method comprising:

a) providing a polymer premix containing a swellable polymer swelled with a swelling agent, the swellable polymer being a thermoplastic polymer not miscible within the swelling agent;
the polymer premix being at a temperature greater than a softening temperature of the swellable polymer;
and
b) mixing the polymer premix of step a) with particles of an electrically conductive material, the mixing being performed at a temperature of at least 50° C. and at most 250° C. and configured to uniformly disperse the electrically conductive particles within the polymer premix so as to obtain the transferable conductive composition in the form of a homogeneous matrix.
