Despite the unique features of poly-L-lactic acid (PLLA), its mechanical properties, such as the elongation at break, need improvement to broaden its application scope. Herein, poly(1,3-propylene glycol citrate) (PO3GCA) was synthesized via a one-step reaction and evaluated as a plasticizer for PLLA films. Thin-film characterization of PLLA/PO3GCA films prepared via solution casting revealed that PO3GCA shows good compatibility with PLLA. The addition of PO3GCA slightly improves the thermal stability and enhances the toughness of PLLA films. In particular, the elongation at break of the PLLA/PO3GCA films with PO3GCA mass contents of 5%, 10%, 15%, and 20% increases to 172%, 209%, 230%, and 218%, respectively. Therefore, PO3GCA is promising as a plasticizer for PLLA.

“…Poly(1,3-propanediol) (PO3G) is a 100% bioderived renewable polyether polyol developed by DuPont [26,27], which has repeating units similar to PEG and PPG. Therefore, PO3G may also have a plasticizing effect on PLLA, but no studies have been reported.…”

Poly(1,3-propanediol palmitate)/L-polylactic acid (PO3G-PA/PLLA) composite films were prepared by solution casting. The two raw materials used to prepare the film are 100% renewable. The experimental results of the composite films show that the addition of PO3G–PA can significantly improve the toughness and crystallinity of PLLA while keeping the thermal stability of the film unchanged. When PO3G–PA was added to the film at concentrations of 0%, 5%, 10%, 15%, 20%, and 25%, the elongation at break of the film reached 37.5%, 68.8%, 118.9%, 226.8%, and 95.9%, respectively. The crystallinity of PLLA could reach 4.5%, 6.19%, 10.59%, 23.00%, 25.28%, and 16.62%, separately. The accelerated degradation experiments at 60 °C showed that adding different quantities of PO3G-PA under neutral conditions had a minimal effect on the rate of PLLA film degradation. The degradation rate of the PLLA membrane can be successfully modified by varying the concentration of PO3G–PA under acidic and alkaline conditions.

“…Bio‐based 1,3‐propanediol (1,3‐PDO) is corn‐derived raw materials, and is used to acquire 100% renewably sourced poly(trimethylene ether) glycol (PO3G) through polycondensation 9 . The renewable PO3G has been used as key ingredients in preparing reactive hot melt adhesive, 7 micelles, 10 and elastomers 11 . In our recent work, 12 bio‐based WPU based on PO3G (WPU‐PO3G) was prepared to reveal superior flexibility, abrasive‐ and hydrolysis‐resistance in comparison with petroleum poly(tetramethylene ether) glycol‐based WPU.…”

A series of fluorinated waterborne polyurethane (FWPU) with different fluorine contents were synthesized via a self‐emulsifying method from 100% renewably sourced poly(trimethylene ether) glycol and perfluoropolyether (PFPE). All the FWPU dispersions exhibited good storage stability with average particle size ranging from 65 to 85 nm. Compared with the neat WPU, the water contact angle of FWPU‐15 film was significantly increased to 100° when the PFPE content was 15 wt%, and the surface tension was reduced to 19.9 mN/m. The hydrophobicity of the FWPU films was further enhanced after being annealed at 140°C for 3 h due to the migration of fluorine‐containing segments to the surface as revealed by x‐ray photoelectron spectroscopy and atomic force microscopy analysis. With the introduction of PFPE in FWPU, the micro‐phase separation between hard and soft segments was increased. Meanwhile, the tensile strength, hardness, and modulus of the films were significantly enhanced. The FWPU films exhibited excellent water resistance (water absorption down to 4.8%) and coating properties. Overall, this work provides a new kind of bio‐based waterborne polyurethane materials with superior hydrophobic properties, which have potential applications in coating fields.
