Hydrophobic materials examples
WebSynthetic hydrophobic polymers can be subdivided into two groups: 1. Prepolymerized: These polymers are prepolymerized from their monomers and thereafter used for nanocarrier preparation. They include poly (ε-caprolactone) (PCL), poly (lactic acid) (PLA), poly (D,L-lactic-co-glycolic acid) (PLGA), and polystyrene. 2.
