Authors have claimed a filtration efficiency of 99.98% without sufficient detail on testing conditions or types of particulate matter used, making it difficult to comprehend if these results could apply to real-world mining environments.
Moreover, while they have discussed membrane’s moisture permeability, they have presented little information on its long-term durability and performance under continuous use, which is critical for coal mining applications.
The scalability of the electrospinning process is not addressed either, leaving uncertainty about the feasibility of mass production.
Also, would you also share insights on the impact of parameters like spinning time and precursor concentrations on efficiency and comfort? The absence of these have limited the practical understanding of the membrane’s performance in diverse conditions.
Authors` explanations of the above are highly appreciated.
