this technology to other plastics. In addition to the anchored plasticizer nanoparticles developed for PVC, TDA also gained knowledge that allowed for the development of additional applications, such as impact modifiers and nanoparticles as carriers for colorants and antimicrobials. Company History TDA Research, Inc., was founded in 1987 and is
Effects of plasticizers on the structure and properties
For conventional starch-based films, glycerol is the most commonly used plasticizer. In order to further investigate the role of plasticizers on the formation of nanocomposite structure, two different plasticizers (urea and formamide) with amide groups were selected for the preparation of starch–clay nanocomposites. Glycerol was used as a

If properly designed, the plasticizing nanoparticles would show good dispersion without the loss in physical properties observed with larger particle fillers. TDA Research, Inc. (TDA) has shown that plasticizers anchored on nanoparticles can soften PVC, but cannot escape from the polymer.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.

- What are polymer nanocomposites used for?
- The polymer nanocomposites may be used in water treatment, sensor, electromagnetic shielding and food packaging. This is attributed to the improved properties exhibited by the polymer nanocomposites compared to the original polymer.
- How do nanocomposite films disperse CNCs into EVOH?
- Excellent dispersion of CNCs into EVOH was achieved by compounding premixed monolaurin and CNCs, prepared by codissolution/evaporation in a suitable ethanol/water cosolvent. Nanocomposite films with effective CNC dispersion prepared in this study also showed enhanced mechanical, thermal, and water barrier properties.
- Can nanocomposite film be used in antimicrobial packaging applications?
- Pirsa et al. developed a novel nanocomposite film based on bacterial cellulose, ZnO NPs, and polypyrrole, which may be useful in antimicrobial active and smart packaging applications .
- What type of application is a nanocomposite suitable for?
- The preparation method and the types of nanofillers are important factors in determining the type of application a nanocomposite would be suitable for. The polymer nanocomposites may be used in water treatment, sensor, electromagnetic shielding and food packaging.
- What are the advantages of nanocomposites?
- Nanocomposites comprising polymers integrated with nanomaterials exhibit improved properties, such as enhanced resistance to fouling, thermal stability, membrane permeability, good mechanical behavior, higher photocatalytic activity, and higher adsorption .
- Are polymer nanocomposites the future of material science?
- Polymer nanocomposites hold great importance in the progress of material science. The promising physical and chemical properties of the components of PNCs would enable extending the smart behaviors to material applications. However, much remains to be investigated regarding these systems.
