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-

TDA proposes to increase the permanence of plasticizers by attaching the plasticizer to the surface of a nanoparticle. The anchored plasticizer still affects the glassy-to-rubbery transition of the host material, yet the permanence of the plasticizer is substantially increased.
Final Report | Nanocomposite Anchored Plasticizers | Research
The additional benefit of increased plasticizer permanence also was discovered with the addition of TDA’s nanoparticles. In PVC formulations plasticized with 50 phr dioctylphthalate (DOP), the addition of small (2-5 percent) amounts of TDA’s nanoparticles significantly decreased the percent of plasticizer lost to air, activated carbon
The synthesis of silver-nanoparticle-anchored electrospun
The preparation of as-spun silver–polyacrylonitrile composite nanofibers (Ag/PAN Com) and the in situ synthesis of silver nanoparticles anchored on the surface of PAN nanofibers were presented. The former were directly electrospun from the solution of PAN and silver nitrate (AgNO3). The latter (AgNPs/PAN) were prepared by immersing as-spun PAN nanofibers in AgNO3 aqueous solutions with
- 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.
- What is the global market for non-phthalate plasticizers?
- Looking in more detail at the global market for non-phthalate plasticizers, M&M's report estimates that the value of this sector will reach US$1.55 billion in 2017 and grow at a CAGR of 8.7% in the intervening years to $4.53 billion by 2022.
- 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.
- Can plasticizers be used to make plastic products?
- The use of plasticizers for plastic products manufacture is not a new practice. Its application to modify polymer characteristics began in the 1800s. In these early days, manufacturers of celluloid or celluloid lacquers used natural camphor and castor oil for plasticization purposes, but these were unsatisfactory for many end uses.
- What is the growth rate of non-phthalate plasticizers?
- The latest report from MarketsandMarkets (M&M) confines itself to the non-phthalate plasticizers, forecasting a compound annual growth rate (CAGR) of 8.7% in value terms from 2017 to 2022 for this sector.
