PDMSmasks4ALL
Aims to apply state-of-the-art technologies to develop polydimethylsiloxane (PDMS) masks to protect COVID-19.
In addition to its transparency, this masks have other advantageous properties, such as biocompatibility, gas permeability and flexibility.
INTRODUCTION
Nowadays, the acute respiratory syndrome (SARS COV 2 that causes Covid 19 has become a global pandemic. Have been taken measures to slow down the spread of the virus, including social distance and the use of personal protective equipment (PPE). Masks became one of the indispensable pieces during the pandemic, but the current models hinder interpersonal
communication, cause environmental problems, additionally they cause irritation and skin discomfort
RESULTS AND DISCUSSION
The final models were obtained using molds manufactured in polysmooth and polyurethane resin The obtained models seem to be proomising however is possible to improve in the near future.
The polysmooth mold did not present the best surface finishing, so the model decreases the optical transparency. The resin mold presented a better surface finish.
