Abstract
An organogel including a base fluid, cetyl alcohol, and a gelling agent provided in an amount to cause the fluid to change from a liquid state to a gelled state at temperatures below at least 25° C. A nanofluid including an organogel and a nanoparticle component which permits the nanofluid to change from a liquid state to a gelled state at temperatures below at least 25° C., the gelled state helping to maintain the nanoparticle component suspended throughout the base fluid; and a method for preparing a gelled nanofluid.
Claims8
An organogel comprising:
- a base fluid which is 2-hexyl-1-decanol or 2-n-octyl-1-dodecanol,
- cetyl alcohol, and
- a gelling agent provided in an amount to cause the fluid to change from a liquid state to a gelled state at temperatures below at least 25° C.,
- wherein the concentration of cetyl alcohol is 1% to 15% by weight based on the total weight of the organogel,
- the concentration of the gelling agent is 0.1% to 2% by weight based on the total weight of the organogel,
- the concentration of the base fluid in the organogel is 83% to 98.9% by weight based on the total weight of the organogel, and
- the gelling agent is sodium oleate.
A method of preparing a gelling nanofluid, the method comprising the steps of:
- preparing an organogel containing a base fluid, cetyl alcohol, and a gelling agent, combining the organogel with a nanoparticle component, to form a gelling nanofluid;
- and
- cooling the gelling nanofluid to a temperature of less than 25° C., which changes from a liquid state to a gelled state at temperatures below 25° C., the gelled state helping to maintain the nanoparticle component suspended throughout the base fluid,
- wherein the concentration of cetyl alcohol in the organogel is 1% to 15% by weight based on the total weight of the organogel,
- the concentration of the gelling agent in the organogel is 0.1% to 2% by weight based on the total weight of the organogel,
- the concentration of the base fluid in the organogel is 83% to 98.9% by weight based on the total weight of the organogel,
- the base fluid in the organogel is 2-hexyl-1-decanol or 2-n-octyl-1-dodecanol, and
- the gelling agent is sodium oleate.
