Abstract
A resin composition comprising a polyolefin, carbon nanotubes and poly(hydroxy carboxylic acid). The invention also covers a process for preparing a resin composition comprising a polyolefin, carbon nanotubes and poly(hydroxy carboxylic acid) by (i) blending a poly(hydroxy carboxylic acid) with carbon nanotubes to form a composite (ii) blending the composite with a polyolefin. The use of poly(hydroxy carboxylic acids) as a compatibilizer to blend carbon nanotubes into polyolefins is also claimed.
Claims20
A process for preparing a resin composition comprising:
- blending a poly(hydroxy carboxylic acid) with carbon nanotubes to form a composite, wherein the blending of the poly(hydroxy carboxylic acid) with the carbon nanotubes comprises solution processing, dry blending, dry blending and melt blending, or melt blending;
- and
- blending the composite with a polyolefin to form the resin composition.
A resin composition comprising a polyolefin and a composite comprising carbon nanotubes and poly(hydroxy carboxylic acid), wherein the poly(hydroxy carboxylic acid) and the carbon nanotubes are blended via solution processing, dry blending, dry blending and melt blending, or melt blending.
A process for preparing a resin composition comprising:
- polymerizing hydroxy carboxylic acid monomers to form poly(hydroxy carboxylic acid);
- blending the poly(hydroxy carboxylic acid) with carbon nanotubes to form a composite;
- and
- blending the composite with a polyolefin to form the resin composition, wherein the composite comprises the carbon nanotubes dispersed within the poly(hydroxy carboxylic acid).
