Накратко на български

Въглеродните нанотръби се изследват за създаването на филтри, които да пречистват водата от вируси и остатъци от лекарства. Това е важно, за да се подобри достъпът до чиста питейна вода и да се премахнат трудните за третиране замърсители.

Engineered multi-scale carbon materials

Access to clean water is a human right and is fundamental to maintaining the basic standards of public health. Nevertheless, the United Nations is estimating that over a billion individuals are lacking access to potable water. At the same time, wastewater treatment is becoming increasingly challenging as it needs to address not only classic pollutants but also viral, microbial and other organic contaminants, such as surfactants, disinfection by-products, and pharmaceuticals. Carbon nanotube (CNT) based filters have the potential to revolutionize water treatment, because of their ability to rapidly remove large amounts of various pollutants from numerous liquids. Despite significant commercial activities, CNTs have not yet found widespread applications in water filtration. Most reports on CNT filters rely on powders, colloidal particles, spherical aggregates, or foams suspended in a beaker to adsorb the pollutants. However, these approaches are not scalable because they have low filtration rates, the recovery of CNTs after filtration is challenging, and their filter regeneration cycles are complex and cumbersome. A popular alternative approach is to work with immobilized CNT membranes, which eliminate the need for dispersing and recovering the nanotubes. However, such membranes offer only very limited retention of pollutants and suffer from extremely low filtration rates. Further, fabrication of CNT membranes with controlled geometries, porosity and pore shape, still remains a challenge. Water filtration in particular requires engineering of CNT order, morphology, and porosity at several length scales to create highly ordered 3D structures to be used as filters. This project developed a new process that addresses these challenges by assembling CNTs into microstructures using microfluidic emulsification followed by large area into colloidal crystals. This approach provides a novel scalable route to sequentially engineer nano-, micro-, and macroscale material architecture. The CNT microparticles and their macroscale colloidal crystals developed in this project have, for the first time, enabled a high performance CNT filter and will, in the near future, enable high performance catalysts and energy devices.

Цел на проекта

Over the past years, industrial interest in carbon particles such as carbon nanotubes (CNTs) and graphene has resulted in low cost mass production of these materials at low cost. For commercialization purposes it was essential to integrate these new materials with existing high-throughput manufacturing methods such as injection moulding. Unfortunately, these processes result in un-organized CNT arrangements whose figures of merit typically drop by an order of magnitude compared to what is measured in individual nanoparticles. Some of the most promising future applications of CNTs and graphene, such as high density energy storage and water filtration however require engineering of order, morphology, and porosity at several length scales to create highly ordered 3D structures. In this project, we propose a new process which assembles CNTs and/or graphene into microstructures using microfluidic emulsification followed by large area self-assembly into colloidal crystals. This approach provides a novel scalable route to sequentially engineer nano-, micro-, and macroscale material architecture. The ability to engineer multi-scale material structure will be harnessed to fabricate new high performance water filtration devices. Further, this project will impact other diffusion limited processes such as energy storage, catalysis, and photovoltaics.
