Preparation and characterisation of compatibilised polycaprolactone/starch composites

Physical properties and biodegradability of maleated-polycaprolactone/starch composite

“…1(A) and (B) shows the FTIR spectra of unmodified PCL and PCL-g-MAH, respectively. The characteristic peaks of PCL [16,19] at 3300- 3700, 1737, 1725, 850-1480 and 720 cm À1 all appeared in both polymers, while extra peaks at 1786 and 1860 cm À1 were observed in PCL-g-MAH. Yu et al [20] indicated that peaks of FTIR spectra at 1781 and 1857 cm À1 represent anhydride functional groups of maleic anhydride, as have others [18,21,22].…”

“…Studies by Bikiaris and Panayiotou [14] showed that maleic anhydridegrafted-polyethylene (PE-g-MAH) increased the compatibility between low-density polyethylene (LDPE) and plasticized starch. This suggests that the blending of PCL with the cheaper material starch, with a reactive functional group grafted onto PCL to improve adhesion and dispersion of the two immiscible phases, offers the best combination of cheapness and good mechanical properties [15,16].…”

Microstructure, Thermal Properties and Rheological Behavior of PLA/PCL Blends for Melt-blown Nonwovens

“…The used in eq. (1) was 93 J/g for PLA 22 and 136 J/g for 23 TGA: TGA of pure PLA and PLA/PCL blends was performed on a Perkin Elmer Pyris to study their thermal stability. The scanning rate was at 10 o C/min and the temperature range was from 23 to 600 o C in N 2 atmosphere.…”

“…Such high crystallinity of PCL was previously reported by several authors. [28][29][30] The X cx values of PLA/PCL blends are always smaller than that of pure PLA and decreased with increase of PCL content, which con- …”

Structure, properties and interfacial interactions in poly(lactic acid)/polyurethane blends prepared by reactive processing

“…In order to improve compatibility and achieve a more advantageous combination of properties, several methods have been applied, e.g. the addition of block copolymers such as PCL-PLA diblock [33][34][35], triblock [33,36,37] and random copolymers, a PCL-PEG copolymer [38], a PEO-PPO-PEO triblock copolymer [39] or several commercial impact modifiers [40] compatibilizers [41][42][43]. The method possesses considerable potential, since structure and properties can be controlled relatively easily by the proper selection of components, blend composition and processing conditions.…”
