  • Which plasticizer is best for chitosan film?
  • Besides, considering the plasticization efficiency and storage stability for chitosan films, GLY and PEG showed to be more suitable than EG and PG. Furthermore, a plasticizer concentration of 20% (w/w) with GLY or PEG was sufficient to obtain flexible chitosan film, exhibiting good stability for 5 months of storage.
  • Can plasticizers reduce material degradation over time?
  • The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
  • Which plasticizer has a good plasticizing efficiency?
  • Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
  • Why are plasticizers prone to migration?
  • Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks. However, when incorporated in the polymer matrix, plasticizers are prone to migration. CA products can suffer embrittlement, cracking, warping, or discoloration during their life cycle, affecting the material’s integrity and durability.
  • Which plasticizer has the lowest volatility?
  • The Red Curve Shows Volatility, the Blue Curve Compatibility, and the Green Curve Shows the Solubility Temperature. Plasticizers like DINP and DIDP would typically offer the lowest volatility among the general-purpose plasticizers and good retained mechanical properties after aging.
  • Can methyl-substituent be used as a plasticizer?
  • This illustrates the positive impact of the methyl-substituent (as a result of the structure of the bio-based raw material for 3) for reaching the desired oily form for an application as a plasticizer product. Structure of investigated plasticizers in consideration of their 3D-structure. DEHA (DOA): di (2-ethylhexyl) adipate (dioctyl adipate).
