T171 0-114 Sentence denotes The particle capture of an electret filter is contributed by both mechanical and electrostatic capture mechanisms.
T172 115-347 Sentence denotes An electrostatic capture mechanism significantly improves the quality factor (filtration performance per a unit resistance); and when the surface charges are decayed, filtration mostly depends on the mechanical capture of particles.
T173 348-581 Sentence denotes It is well accepted that IPA treatment removes the surface charges of filter media; therefore, the IPA-treated samples can be deemed as the mechanical filter (mechanical contribution noted as “mech. cont’n”) (Figure 2 and Figure 3B).
T174 582-737 Sentence denotes The performance above this level of filtration for the untreated respirators A and B is considered as the electrostatic capture mechanism (electr. cont’n).
T175 738-1013 Sentence denotes Disinfection treatments such as solvent immersion, UV, oven-dry, and microwaving seemed to have negligible impacts on the structural integrity (Figures S3 and S4); accordingly, there were no apparent changes in the resistance and mechanical filtration after those treatments.
T176 1014-1131 Sentence denotes Notable fiber damage was found in the laundered samples by the external force imposed during laundering (Figure S3A).
T177 1132-1160 Sentence denotes The physical damage of Resp.
T178 1161-1309 Sentence denotes A resulted in the decrease of resistance and mechanical filtration performance, corresponding to the lower filtration efficiency compared with Resp.
T179 1310-1312 Sentence denotes B.
