Abstract
Disclosed are compositions, such as sealant compositions, that include a sulfur-containing polymer and graphenic carbon particles.
Claims25
A composition comprising:
- (a) a sulfur-containing polymer comprising at least one of a polysulfide and a polythioether, wherein the sulfur-containing polymer is present in an amount of at least 30 percent by weight, based on the total weight of non-volatile components in the composition;
- and
- (b) graphenic carbon particles.
A composition comprising:
- (a) a sulfur-containing polymer;
- and
- (b) graphenic carbon particles having a compressed density of no more than 0.9 g/cm3.
A composition comprising:
- (a) a sulfur-containing polymer;
- and
- (b) graphenic carbon particles, wherein a 0.5% by weight solution of the graphenic carbon particles in butyl cellosolve has a bulk liquid conductivity of at least 100 microSiemens as measured by a Fisher Scientific AB 30 conductivity meter.
