A semicrystalline plastic composition comprising: a semicrystalline plastic and an additive dispersed therein. The semicrystalline plastic includes a polymeric chain comprising repeat units of an oligomeric or polymeric chain and the additive comprises a supramolecular building block and an oligomeric or polymeric tail. The oligomeric or polymeric tail of the additive having the same repeat units as the polymeric chain of the semicrystalline plastic. The additive forming a plurality of sheet-like structures through hydrogen bonding. The sheet-like structures, interacting through non-covalent interaction, form crystallized additive domains within the semicrystalline plastic.
