Claims18
An ultraviolet (UV) light stabilizing polymeric filler material that includes a particle that is surface modified to include a hydroxyphenyl-benzotriazole (HPB) derivative functionality, forming a Janus particle, wherein the Janus particle comprises:
- a first portion of a surface of the Janus particle, the first portion surface modified to include the HPB derivative functionality, and
- a second portion of the surface of the Janus particle, the second portion surface modified to include a second functionality, wherein the second portion is different than the first portion.
A process of forming an ultraviolet (UV) light stabilizing polymeric filler material, the process comprising:
- surface modifying a first portion of a surface of a silica particle to include a hydroxyphenyl-benzotriazole (HPB) derivative functionality, forming a silica Janus particle;
- and
- surface modifying a second portion of the surface of the silica Janus particle to include a second functionality, wherein the second portion is different than the first portion.
An article of manufacture comprising:
- a polymeric material;
- and
- an ultraviolet (UV) light stabilizing polymeric filler material that includes a silica particle that is surface modified to include a hydroxyphenyl-benzotriazole (HPB) derivative functionality, forming a silica Janus particle, wherein the silica Janus particle comprises:
- a first portion of a surface of the silica Janus particle, the first portion surface modified to include the HPB derivative functionality, and
- a second portion of the surface of the silica Janus particle, the second portion surface modified to include a second functionality, wherein the second portion is different from the first portion.
