摘要:
A mesoporous ceramic material is provided having a pore size diameter in the range of about 10-100 nanometers produced by templating with a ceramic precursor a lyotropic liquid crystalline L3 phase consisting of a three-dimensional, random, nonperiodic network packing of a multiple connected continuous membrane. A preferred process for producing the inesoporous ceramic material includes producing a template of a lyotropic liquid crystalline L3 phase by mixing a surfactant, a co-surfactant and hydrochloric acid, coating the template with an inorganic ceramic precursor by adding to the L3 phase tetramethoxysilane (TMOS) or tetraethoxysilane (TEOS) and then converting the coated template to a ceramic by removing any remaining liquids.
摘要:
Ultra smooth ceramic materials are prepared by the low temperature sintering of a ceramic body that has been infiltrated prior to sintering with an inorganic polymer. The infiltration allows for a decrease in the sintering temperature which translates into a smoother, stronger ceramic material.

Graphene tapes made by forming a film comprising graphene sheets and at least one polymeric binder and heating the film to decompose the polymer. The tapes may be used as electrodes.
