The SAS coating solution was prepared with a 10 wt% ethanol base concentration, and 1 wt% PFOTES (Sigma-Aldrich) was added to the solution to form SAS/PFOTES. Then 3 mM CV (Sigma-Aldrich) was mixed under steady agitation to form SAPC. Polypropylene melt-blown fabric with a basis weight of 32 g m−2 was procured from Filter Factory (CNS Industry, Suwon, Korea) (Table S1). All filter media were cleaned successively with acetone, ethanol, and isopropyl alcohol in an ultrasonic bath for 15 min each, and then oven-dried at 50 °C. The cleaned filters were treated with O2 plasma for 3 min and dip-coated into the SAPC solution at a withdrawal rate of 0.5 mm s−1 (Fig. S1 ). The coated filters were cured at 50 °C for 2 h. The SAPC filters were rinsed with deionized water to remove residues and rounded to a 25.4 mm diameter to evaluate filtration and VLD antimicrobial performance.

CFR panels with a size
of 7.5 × 2.5 × 0.1 cm3 have been used as substrates.
CFR panels are commonly used as structural materials in the manufacturing
of aircraft and their components. The hemp fabric rugs were supplied
by MAEKO S.r.l. (Milan, Italy). Sodium metasilicate (Na2SiO3, waterglass), APTES (>98%), hydrochloric acid
(37
wt %), PPgMA with 8–10 wt % maleic anhydride content and an
average Mw ∼ 9100 by gel permeation
chromatography (GPC), HDTMS (>85%), and PFOTES (98%) were purchased
from Sigma-Aldrich (Merck KGaA, Darmstadt, Germany). A two-component
epoxy resin system (SX10), consisting of a modified diglycidyl ether
of bisphenol-A (DGEBA) resin and isophorone diamine (IDA), a cycloaliphatic
diamine hardener, purchased from MATES S.r.l. (Milan, Italy), was
used for the preparation of the polymer matrix in the composite coatings.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
