Abstract
A method for coating a non-metallic substrate with a polymer solution that includes an aromatic polyester and a solvent is provided. By selectively controlling the nature of the aromatic polyester, the present inventors have discovered that such polymer solutions can be readily formed, thereby enabling the use of simpler and less complex techniques (e.g., solvent casting) for coating substrates with aromatic polyesters. Moreover, the nature of the polyester and its relative concentration in the solution can also be tailored to achieve coatings that not only adhere well to the substrate, but also possess good thermal and mechanical properties for use in a wide variety of potential applications.
Claims28
A method for forming a laminate that contains a coating on a non-metallic substrate, the method comprising:
- applying a polymer solution to the non-metallic substrate, wherein the polymer solution comprises a solvent and an aromatic polyester containing aromatic biphenyl units having the following general Formula I and aromatic ester units having the following general Formula II;
- and
- wherein,
- R5 and R6 are independently halo, haloalkyl, alkyl, alkenyl, aryl, heteroaryl, cycloalkyl, or heterocyclyl;
- m and n are independently from 0 to 4;
- X1 and X2 are independently O, C(O), NH, C(O)HN, or NHC(O);
- Z is O or SO2,
- ring B is a substituted or unsubstituted 6-membered aryl group, a substituted or unsubstituted 6-membered aryl group fused to a substituted or unsubstituted 5- or 6-membered aryl group, or a substituted or unsubstituted 6-membered aryl group linked to a substituted or unsubstituted 5- or 6-membered aryl group;
- and
- Y1 and Y2 are independently O, C(O), NH, C(O)HN, or NHC(O), wherein at least one of Y1 and Y2 are C(O);
- thereafter, removing the solvent to form the coating on the substrate.
A laminate comprising a coating that is disposed on a non-metallic substrate, wherein the coating comprises an aromatic polyester containing aromatic biphenyl units having the following general Formula I and aromatic ester units having the following general Formula II:
- wherein,
- R5 and R6 are independently halo, haloalkyl, alkyl, alkenyl, aryl, heteroaryl, cycloalkyl, or heterocyclyl;
- m and n are independently from 0 to 4;
- X1 and X2 are independently O, C(O), NH, C(O)HN, or NHC(O);
- Z is O or SO2;
- ring B is a substituted or unsubstituted 6-membered aryl group, a substituted or unsubstituted 6-membered aryl group fused to a substituted or unsubstituted 5- or 6-membered aryl group, or a substituted or unsubstituted 6-membered aryl group linked to a substituted or unsubstituted 5- or 6-membered aryl group;
- and
- Y1 and Y2 are independently O, C(O), NH, C(O)HN, or NHC(O), wherein at least one of Y1 and Y2 are C(O).
