Abstract
A soundproof member is provided. The soundproof member includes a structural element, and a first composite film which is disposed on the bottom surface of the structural element. The structural member includes at least one through hole and the through hole passes through the structural element. The first composite film includes a polymer material and an inorganic nanoscale material, wherein the inorganic nanoscale material is a one-dimensional inorganic nanoscale material or a two-dimensional inorganic nanoscale material.

A soundproof member, comprising:
- a structural element, wherein the structural member includes at least one through hole passing through the structural element and extending in a first direction, and the first direction is perpendicular to a bottom surface of the structural element;
- and
- a first composite film disposed on the bottom surface of the structural element, wherein the first composite film includes at least one first micro cavity, wherein the first micro cavity is disposed in the first composite film and extends in a second direction, and the second direction is parallel to the bottom surface of the structural element and perpendicular to the first direction, wherein the first composite film has a porosity of 30% to 60%, wherein the first micro cavity has a maximum length L1 in the first direction, the first micro cavity has a maximum length L2 in the second direction, and L1/L2 is 0.01 to 0.5.
A soundproof member, comprising:
- a structural element, wherein the structural member includes at least one through hole passing through the structural element;
- and
- a first composite film disposed on a bottom surface of the structural element, wherein the first composite film comprises a polymer material and an inorganic nanoscale material, wherein the first composite film has a porosity of 30% to 60%, wherein the inorganic nanoscale material and the polymer material have a weight ratio of 1:10 to 2:1.
