Graphite Exfoliation Method

Номер: US20170029280A1
Автор: Divigalpitiya Ranjith, Julius David, Korba Gary A., Zin Melvin
Принадлежит:

A method of producing an aqueous dispersion of few-layer graphene nanosheets is disclosed, the method including: (a) mixing graphite particles with a perfluorosulfonate ionomer in an aqueous liquid, to form an aqueous dispersion of graphite particles; and (b) sonicating the aqueous dispersion of graphite particles to form an aqueous dispersion of few-layer graphene nanosheets, wherein the perfluorosulfonate ionomer is disposed as a thin and continuous layer on the few-layer graphene nanosheets. A composition is also disclosed, comprising an aqueous dispersion of a mixture of: (a) a perfluorosulfonate ionomer; and (b) a plurality of few-layer graphene nanosheets; wherein the perfluorosulfonate ionomer is disposed as a thin and continuous layer on the few-layer graphene nanosheets. 2. The method of claim 1 , wherein claim 1 , prior to the sonicating claim 1 , a concentration of the graphite particles in the aqueous dispersion of graphite particles is in a range from 0.5 mg/mL to 5 mg/mL claim 1 , relative to a total volume of the aqueous dispersion of graphite particles.3. The method of or claim 1 , wherein prior to the sonicating claim 1 , a weight ratio of the perfluorosulfonate ionomer to the graphite particles in the aqueous dispersion of graphite particles is in a range from 0.1:1 to 10:1.4. The method of claim 1 , wherein the aqueous dispersion of few-layer graphene nanosheets further comprises a water-miscible solvent.5. The method of claim 1 , wherein the water-miscible solvent is a C1 to C4 alcohol.6. The method of claim 5 , wherein the water-miscible solvent is ethanol.7. The method of claim 1 , wherein a volume ratio of the ethanol and water in the aqueous dispersion of few-layer graphene nanosheets is in a range from 0.5:1 to 1.5:1.8. The method of claim 1 , wherein the sonicating is carried out for no more than 24 hours.9. The method of claim 1 , wherein the aqueous dispersion of few-layer graphene nanosheets remains dispersed for a period of at least one ...

Microneedle applicator comprising a counter assembly

Номер: US20160271380A1
Автор: Boon Yi Soon, Chi Ying Lee, David Julius, Mei-Ling Pan, Melvin Zin, Yarn Chee Poon
Принадлежит: 3M Innovative Properties Co

A microneedle applicator. The applicator can include a microneedle array, a microneedle array holder, and an actuator movable between a first position and a second position to cause the microneedle array holder to move, respectively, between a retracted position and an extended position. The applicator can further include a first biasing element configured to bias the actuator in the first position, and a counter assembly, or mechanism, configured to count a number of times the microneedle array holder is moved between the retracted position and the extended position (or the number of times the actuator is moved from the first position to the second position). In some embodiments, the counter assembly can include the actuator and first biasing element.
