## Abstract Blends of polycaprolactone (PCL) and chitosan (CHT) were prepared by casting from the mixture of solutions of both components in suitable solvents. PCL, and CHT, form phase separated blends with improved mechanical properties and increased water sorption ability with respect to pure PCL
## Abstract **Summary:** Poly(__ε__‐caprolactone) (PCL)/chitin and PCL/chitosan blend films with compositional gradients were successfully fabricated by a dissolution/diffusion method; that is, repeatedly pouring the PCL/chitin (or PCL/chitosan) blend solutions, with variable composition, onto poly
## Abstract Blends of polycaprolactone (PCL) and chitosan (CHT) were prepared by casting from a solution. CHT and PCL were dissolved by using acetic acid/water mixtures. Both solutions were slowly mixed to cast blend films containing 10%, 20%, 30%, and 40% by weight of CHT. PCL and CHT form phase s
