Synergistic effect of organic plasticizer and lepidolite
PEO is the most popular polymer as a matrix of CPEs; however, it has many shortcomings. PVDF can be considered as a potential matrix, with a wide electrochemical window, flame retardance and high thermal stability; on the other hand, it has always shown low ionic conductivity.
Natural-based plasticizers and biopolymer films: A review
Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives [1]. The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature ( Tg ).
New oligoether plasticizers for poly(ethylene oxide)-based
For NOE plasticizers, the potential was anodically scanned from 2.0 to maximum 5.0 V versus Li/Li + at a scan rate of 10 mV/s. The thermal stability of SPE films has been tested by Mettler thermogravimetric analyzer (TGA).
Long- and short-term stability of plasticized poly(lactic
The aim of this study is to investigate the property stability of plasticized PLA for a time period of 2 years starting from the production. We have used three grades of PEG with different molecular weights such as 400, 8000, and 35,000 g/mol, namely PEG-400, PEG-8000, and PEG-35,000 in various concentrations such as 0, 5, 10, 15, and 20 wt%.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are bulky organic molecules, generally 300–600 g/mole in molecular weight, and also somewhat polar so as to be compatible with the PVC matrix. Good plasticization involves interspersing plasticizer molecules between PVC chains, breaking the small amount of native PVC crystallinity, and internally lubricating the polymer blend.
- Are bio-based plasticizers sustainable?
- On one hand, bio-based plasticizers consist of plasticizers derived from renewable bio sources such as biomass, plant oils, and fats. They are usually more sustainable than petrochemical-based plasticizers due to the use of renewable materials along with a lower carbon footprint.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Can biobased plasticizer be used as a heat stabilizer?
- The plasticizing effect of single biobased plasticizer is not good. Biobased plasticizer with synergistic effects is required. There exists the trade-off effect between the molecular weight and the compatibility. Epoxidized isosorbide ester can be used as a heat stabilizer. The authors declare that they have no conflict of interest.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Can ricinoleic acid make a high-stability bio-based plasticizer?
- In this work, a new type of high-stability bio-based plasticizer was obtained by a four-step reaction with ricinoleic acid as main raw material, and its structure was characterized and identified by FT-IR and 1 H NMR.
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
