| Summary: | This study aims to develop
an additional layer in masks using micro-carbon to enhance protection against
inhalation of droplets. Carbon microstructures were obtained using spray
pyrolysis method, with the precursor being resina colophonium dissolved in acetone
and ethyl acetate. Subsequently, the effect of varying the precursor-solvent
ratio, heating temperature, and nitrogen flow rate on the shape, size, and
content of the products was assessed. The results showed that the highest
carbon content achieved was approximately 96%, with the smallest size measuring
139 nm. The penetration test results after applying the product on masks fabric
revealed a significant reduction in penetration up to level 2. In addition, the
contact angle test showed that the addition of carbon led to a lower reduction
(6.7°) compared to regular masks fabric with a 20.4° decrease. This improvement
could contribute to reducing the risk of droplet inhalation during masks
application. |
