From examples 1 to 5, it can be seen that the average particle size of the nano-aluminum particles has an influence on the air permeability, and the air permeability is most effective when the average particle size is 20 to 70 nm. From examples 6 to 9, it can be seen that the carbon fibers having a diameter of 5 to 7 μm can be distributed in polypropylene more favorably, and have good mechanical properties and good air permeability; if the carbon fiber diameter is too large, the toughness of the polypropylene is lowered, and if it is too short, the air permeability of the polypropylene resin is increased. From examples 12 to 15, it is seen that when the molecular weight of the polyvinyl alcohol is from 18000 to 20000, a good network structure can be formed, and when the molecular weight is too low, the network structure is loose and the air permeability is increased; the polypropylene resin is easily deteriorated due to an excessively high molecular weight.
From comparative examples 1 to 3, when no nano aluminum particles or polyvinyl alcohol were added, the air permeability effect was poor, indicating that the nano aluminum particles and polyvinyl alcohol were required to act together to reduce the air permeability. When flake aluminum is added, the low air permeation effect is also poor.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
