Purpose: The purpose of this study was to investigate the effect of Carboxylated SWNT (Carbon nanotube, single-walled) on the physical properties of contact lenses.
Methods: One of the samples that were used in the experiment contained HEMA, MMA, NVP, and EGDMA as the basic combination, and was referred to as the reference sample. The samples consisting of 0.09% carboxylated SWNT added to the reference sample were referred to as the Ref.Cn samples. The physical characteristics of contact lens were evaluated by measuring water content, refractive index and tensile strength.
Results: The water content of the prepared contact lens was measured as 38.54 ~ 39.94%, and the refractive index was measured as 1.4328 ~ 1.4330. The tensile strength of contact lenses with carboxylated SWNT were measured at 0.3177 to 0.3333 kfg.
Conclusions: Carboxylated SWNT showed no significant change in water content and refractive index but showed a significant increase in tensile strength.
