Through growth of poly(ethylene glycol) (PEG)-b-poly(ε-caprolactone) (PCL) and PEG-b-poly(L-lactide) (PLLA)
single crystals from dilute solution, the crystallization of crystallizable PCL and PLLA brushes in homo and
mixed-brush nanostructures was investigated. Using various graftings, the physical and chemical environmental
effects were studied on the brush crystallization. The brush interactions were investigated as chemical environmental
effects. The physical environmental effect was also determined by the amorphism/crystallinity and
rigidity/flexibility of neighboring brushes. For this purpose, different single crystals were designed with mixedbrushes
of amorphous-crystalline (polystyrene (PS), poly(methyl methacrylate) (PMMA), PCL and PLLA), double
crystalline (PCL/PLLA), and rod-crystalline polyaniline (PANI)/PCL or PLLA. The type of surrounding brushes
and their miscibility with crystallizable brushes, inherent amorphism or crystallinity, and flexibility or rigidity
were effective on the behavior of crystallizable brushes and induced crystallization procedure. The neighboring
brushes could also prevent the PLLA grafts from crystallization in the presence of PMMA.
