文摘
- •
We investigated fractal properties of quasiperiodic chains diluted in solvent.
- •
Solvent-accessible surface area and volume was calculated for these molecules.
- •
As demonstrated just in an infinity rigid chain the exponents tend to unity.
- •
The molecular flexibility is fundamental for explaining the exponents obtained.
- •
Both classes of macromolecules analyzed present a self-similar characteristic.
