A composition including a polymer and a liquid, wherein the polymer exhibits lower solubility in the liquid at room temperature but exhibits greater solubility in the liquid at an elevated temperature, wherein the composition gels when the elevated temperature is lowered to a first lower temperature without agitation, wherein the viscosity of the composition results from a process comprising (a) dissolving at the elevated temperature at least a portion of the polymer in the liquid; (b) lowering the temperature of the composition from the elevated temperature to the first lower temperature; and (c) agitating the composition to disrupt any gelling, wherein the agitating commences at any time prior to, simultaneous with, or subsequent to the lowering the elevated temperature of the composition to the first lower temperature, wherein the amount of the polymer dissolved in the liquid at the elevated temperature ranges from about 0.2% to about 5% based on the total weight of the polymer and the liquid.

Gelable composition

An electrophotographic imaging member having a charge generating layer and a charge transport layer overlayed thereon is provided. The charge transport layer has a lower surface and an upper surface, wherein the lower surface is in contiguous contact with the charge generating layer. The charge transport layer comprises a film forming polymer binder and a charge transport compound molecularly dispersed or dissolved therein to form a solid solution. The concentration of the charge transport compound in the charge transport layer decreases from the lower surface to the upper surface. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improved wear resistance, excellent imaging member electrical performance, and improved copy print out quality.

Imaging members

A thin film transistor including: an insulating layer; a gate electrode; a semiconductor layer including coalesced structurally ordered polymer aggregates of a self-organizable polymer, wherein the self-organizable polymer is of a type capable of gelling; a source electrode; and a drain electrode, wherein the insulating layer, the gate electrode, the semiconductor layer, the source electrode, and the drain electrode are in any sequence as long as the gate electrode and the semiconductor layer both contact the insulating layer, and the source electrode and the drain electrode both contact the semiconductor layer.
