Abstract
An exemplary embodiment of the present disclosure provides solvent-free cleaning systems and methods, the systems and methods comprise a polymer substrate having a crosslinked matrix positioned on at least one surface of the polymer substrate, wherein the crosslinked matrix is configured to absorb particulates from a surface of a material when placed in direct contact.
Claims30
In a cleaning method comprising:
- contacting a surface of a material having pollutants in a range of sizes with a transfer media;
- and
- transferring at least a portion of the pollutants from the surface via the transfer media;
- wherein at least one of:
- transferring comprises transferring the pollutants having a size greater than a first size from the surface via the transfer media comprising a solution;
- or
- transferring comprises exclusively adsorbing the pollutants having a size less than the first size from the surface of the material to a surface of the transfer media;
- the improvement comprising:
- contacting the surface of the material with a transfer media comprising a solid polymer substrate having a Young's modulus between about 0.01 MPa to about 0.5 MPa;
- transferring at least a portion of the pollutants having a size less than the first size from the surface via an interfacial interaction between the pollutants and the solid polymer substrate;
- and
- absorbing at least a portion of transferred pollutants into the solid polymer substrate;
- wherein the solid polymer substrate has a stronger interfacial interaction with the pollutants than the interfacial interaction between the pollutants and the material.
A cleaning method comprising:
- contacting a surface of a material having particulates directly with a solid polymer substrate having a Young's modulus between 0.01 MPa to 0.5 MPa and a crosslinked matrix positioned on at least one surface of the solid polymer substrate;
- and
- absorbing at least a portion of particulates into the crosslinked matrix of the solid polymer substrate.
A cleaning system a cleaning method comprising contacting a surface of a material having particulates directly with a solid polymer substrate having a Young's modulus between 0.01 MPa to 0.5 MPa and a crosslinked matrix positioned on at least one surface of the solid polymer substrate, and absorbing at least a portion of particulates into the crosslinked matrix of the solid polymer substrate, the cleaning system comprising:
- the solid polymer substrate having the crosslinked matrix;
- wherein the crosslinked matrix is configured to absorb the particulates when placed in direct contact with the surface of the material.
