Core–shell nanoparticle–plasticizers for design of high
Altogether the results show that the nanoparticle –plasticizer concept could be applied to simultaneously improve the toughness and stiffness of the materials and further improvements could be achieved after optimization of the number of PBA chains and their molecular weight. https://doi.org/10.1039/C1JM10624D Article type Paper Submitted
Nanoparticle-Anchored Plasticizers - US EPA
Plasticizers change the properties of a polymer by increasing the free volume between polymer chains, allowing more chain movement, which translates to more flexibility of the softened plastic. TDA has shown that plasticizers anchored to nanoparticles can soften PVC but cannot escape from the polymer. Although the nanoparticles resis-
Effects of Nanoparticle Concentration and Plasticizer
Furthermore, adding plasticizers such as PEG-400, glycerol, xylitol, and sorbitol can improve the temperature sensitivity of PDA. Recent examples of new colorimetric TTIs are plasticized PDA/SiO 2
- 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 bio-based plasticizers replace conventional plastic goods?
- The challenge to implement this new class of natural-based plasticizers matches the increasing interest of material researchers and industries in new bio-based materials, made from renewable resources with the potential, not to totally replace but to reduce the use of conventional plastic goods.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- What is the molecular size of a plasticizer?
- Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) , . The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary forces among them.
- What types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
