An environmentally sustainable plasticizer toughened polylactide
Polylactide (PLA), a most popular green plastic, provides a promising alternative to polymers derived from petroleum, and attracts much interest. 1–3 Because of its renewability, biodegradability, biocompatibility and competitive physical properties, PLA has thus been applied in biomedical materials, packaging, and the automotive industry.
Tailoring and Long-Term Preservation of the Properties of PLA
TBC is one of the most effective plasticizers for PLA, produced using entirely renewable components (i.e., citric acid and n-butanol, as raw materials). Former studies showed that between 10 and 20 wt.% of plasticizer in PLA, results in a higher elongation at break and lower T g compared to the unplasticized PLA [ 40 ].
Direct milling: Efficient, facile, and green method for processing
The strong mechanical properties, low cost, and biodegradability of cellulose nanofibers (CNF) make them particularly appealing in automotive parts, as reinforcements of thermoplastics. Cellulose nanomaterials have an excellent modulus of elasticity (130–250 GPa along the chain axis of a perfect crystal of native cellulose) and therefore offer great prospects to reinforce PA6 ( Zhu et al
- Are green bio-based plasticizers a sustainable cold-resistant plasticizer?
- At present, there is no relevant report on green sustainable cold-resistant plasticizers. Therefore, the green bio-based plasticizers with excellent migration resistance and cold resistance are provided with broad application prospects.
- Are plasticizers better than polymer modifiers?
- Moreover, unlike polymer modifiers, both PPA and plasticizers have the advantages of low cost and good compatibility with asphalt, and the use of plasticizer combined with PPA may provide a new cost-effective method to modify asphalt.
- Do plasticizer modified asphalts improve temperature deformation resistance and elastic recovery?
- The results show that the high temperature deformation resistance and elastic recovery ability of the plasticizer modified asphalts are effectively improved by the addition of PPA, and the improvement degree is positively correlated to the PPA content.
- Do plasticizer modified asphalts have a good storage capacity?
- The results of the thermal storage tests demonstrate that the plasticizer/PPA modified asphalts have excellent storage ability. The FTIR results show that the plasticizers are physically mixed with base asphalt, whereas there is a chemical reaction between PPA and the plasticizer modified asphalts.
- Are there any cold-resistant bio-based plasticizers?
- There is no report about cold-resistant bio-based plasticizers, and this is the first one. Strong acid cation exchange resin is not only a catalyst, but also a ring opener for the following reaction. The PVC plasticized by these cold-resistant bio-based plasticizers basically does not migrate in various extreme environments.
- Can plasticizers be used as asphalt modifiers?
- Currently, studies on combination of plasticizers and other modifiers are still incipient. Polyphosphoric acid (PPA) is an inorganic acid formed by the thermal reactions of phosphoric acid and phosphorus pentoxide. It has been used as an asphalt modifier for more than 30 years .
