Abstract:
The present disclosure relates to a matrix-free polymer nanocomposite. The matrix-free polymer nanocomposite includes a plurality of polymer brush grafted nanoparticles, which form the nanocomposite in the absence of a polymeric matrix. The polymer brush grafted to the nanoparticles comprises a multimodal brush configuration having at least two different populations of polymer ligands of different lengths. The present disclosure also relates to an optic or optoelectronic component comprising a matrix-free polymer nanocomposite as described herein. The present disclosure further relates to a method of making a matrix-free polymer nanocomposite.
Abstract:
An improved method for suspending GTR in asphalt is disclosed. The method allows GTR to be used without the GTR particles settling out of the asphalt blend. The GTR will remain suspended in the asphalt and will not settle for at least 48 hours in the absence of mechanical agitation. In a second aspect, an asphalt composition containing ground rubber is disclosed. In a third aspect of the invention, a pavement structure containing GTR is disclosed.
