CycloPure is commercializing the pioneering polymer technologies discovered by the Dichtel Lab. Using these technologies, the company has developed a new class of highly-adsorbent materials that separate and remove pollutants, VOCs and other organic compounds from water and air.
Highly Adsorbent Cyclodextrin Networks
Combining cyclodextrin with specific, rigid monomers into repeating structures creates a polymer network of high surface area pores with precise adsorption properties.
High Surface Area
CycloPure’s polymers derive their effectiveness by linking cup-shaped cyclodextrin building blocks into porous, high surface area structures.
Adsorption by Encapsulation
The pores form high-affinity pockets into which contaminants are drawn and trapped, making the polymers ideally suited for separation and removal of unwanted compounds from water and air.
By varying the molecular building blocks, the polymer can be altered into
different formulations tailored to the chemical properties of target contaminants.
Rapid Uptake at Low Concentrations
Because of their porous surface area and high-affinity pockets, the polymers are able to bind and rapi dly adsorb pollutants at low concentration. This is important as many contaminants retain potency and toxicity at very low concentration. This highly efficient adsorption process allows water treatment in constant flow installations.
As published in Nature (January 14, 2016), porous cyclodextrin polymers (P-CDP) achieved 95% adsorption of bisphenol A, a component of plastics (BPA), in 10 seconds.
Norit AC (NAC), the next leading adsorbent, achieved contaminant removal in 10 minutes, and only adsorbed 53% of the pollutant in 10 seconds.
Sustainably made with favorable life-cycle characteristics
The company’s science is performed in a material that is sustainable and has environmentally friendly life-cycle characteristics.
The polymers are formed in a single-step reaction using cyclodextrin, a compound made from corn starch.
When fully adsorbed, the material can easily be regenerated through a simple rinsing.
