Friction and wear test results do not meet use requirements

Wear resistance needs to be addressed from modifiers and matrix hardness

Material Analysis wear resistancefrictionmodifierhardness

Improper proportion and selection of formulation components affect modification effect

Formulation needs to balance performance, cost, and compatibility

Material Analysis formulation designcompatibilitycostcellulose acetate butyrate

Transparency of modified cellulose acetate butyrate significantly decreased

Transparency decrease needs to be addressed from refractive index matching and dispersion
