Coating to enhance the efficiency of a particle impact collector

A method for separating particulates from a fluid in which said particulates are entrained, comprising the steps of:

• (a) providing an impact collection surface;
• (b) producing a coated impact collection surface by applying a coating of a material to the impact collection surface that increases a retention of particulates impacting thereon, wherein the material comprising the coating has a further property of attracting only particulates of a specific desired type;
• and
• (c) causing the fluid in which the particulates are entrained to flow toward the coated impact collection surface, said particulates within the fluid being retained by the material and thus separated from the fluid.

A method for separating particulates from a fluid in which said particulates are entrained, comprising the steps of:

• (a) providing an impact collection surface;
• (b) producing a coated impact collection surface by applying a coating of a material to the impact collection surface, the material comprising the coating being characterized by having a first state and a second state while coating the impact collection surface, said material retaining the particulates when in the first state, and releasing the particulates when in the second state;
• and
• (c) causing the fluid in which the particulates are entrained to flow toward the coated impact collection surface, said particulates within the fluid being retained by the material while said material is in the first state, and thus separated from the fluid.

Apparatus for separating particulates from a fluid in which they are entrained, comprising:

• (a) an impact collection surface;
• (b) a fluid path that conveys the fluid with the particulates toward the impact collection surface;
• and
• (c) a coating comprising a material that substantially enhances a retention and a collection of the particulates, by efficiently separating the particulates from said fluid, said material being characterized by being substantially non-tacky, and by readily releasing the particulates retained thereby when the material is wetted.

• (b) a fluid path that conveys the fluid with the particulates toward the impact collection surface;
• and
• (c) a coating comprising a material that substantially enhances a retention and collection of the particulates, by efficiently separating the particulates from said fluid, said material being characterized by its ability to provide an increased retention of particulates impacting thereon when dry, and by having a relatively low coefficient of friction when wetted, so that the particulates that have impacted on the impact collection surface and been retained thereon are readily washed from said surface with a liquid, said material characterized by being hydrophilic when dry, and hydrophobic when wet.
