Abstract
An oil gel capsule includes an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel. A contact part for a vehicle includes an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules including an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel.
Claims20
An oil gel capsule comprising:
- an oil gel comprising an oil and a gelator;
- and
- a surfactant bonded to the oil gel.
A contact part for a vehicle, the contact part comprising:
- an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules comprise:
- an oil gel comprising an oil and a gelator;
- and
- at least one surfactant bonded to the oil gel.
A method for manufacturing a contact part for a vehicle, the method comprising:
- manufacturing oil gels by mixing an oil and a gelator;
- producing a plurality of oil gel capsules by mixing the oil gels and an aqueous surfactant solution to form an aqueous solution;
- recovering oil powder by drying the oil gel capsules and the aqueous solution;
- preparing a first organic solution comprising 2 to 10 wt % of the oil gel capsules by re-dispersing the oil powder in an organic solvent;
