Abstract
The growing concern about environmental issues has become a pressing issue for businesses as the applicable legislation requires more control of any type of hazard that puts human health or the environment at risk. Currently, chemicals are an important aspect of risk assessment and monitoring because of their importance as constituents of the raw materials and their effects on human health and / or the environment.
The aim of this project is developed a microencapsulation device, with reduced content of COVs and reduced risk for Health and Environment. In this work, we report a microfluidic approach, to fabricate monodisperse isocyanate microcapsules with lipophilic cores and polyurethane shells. These microcapsules are generated in a microcapillary microfluidic device we designed using monodisperse O/W emulsion, with high potential application in aeronautic and automobile industries.
The proposed method has advantages of being readily controlled, cost-effective and easy to operate, together with its ability to produce a uniform size. In addition, microfluidics can control the process of encapsulation by varying flow parameters and/or using a proper geometry of microfluidic channels. By microencapsulating the reactive agent, the product is safer for handling by the industry operators, and the activation mechanism can be controlled more precisely (enabling higher flexibility of application / use case scenarios).
The advances made of the current study can be an important contribution in the innovation and development of new methods and products sustainable/green that can, in the future, compete in the market.
