Further Step in the Transition from Conventional Plasticizers

This effect can lead to the disruption of material integrity, migration of the additive to the polymer surface, and the consequent loss of the desired thermal and mechanical properties. GT plasticizer seems to be properly solubilized within the PHB matrix even at high concentrations (20 and 40 phr), as shown in Figure 2a. PHB samples have shown

ranking plasticizers for polymers with atomistic simulations

Ranking Plasticizers for Polymers with Atomistic Simulations

Virgin biopolymers are often brittle and therefore need the addition of plasticizers to obtain the required mechanical properties for practical applications, for example, in bags and disposable kitchen items. In this article, based on a combined experimental and modeling approach, it is shown that it is possible to rank molecules with respect to their plasticization efficiency (depression in

Effect of different polyol-based plasticizers on thermal

The conducted strategy in choosing plasticizer was based on obtaining a series compounds with varying hydroxyl group functionality on the carbon chain. In this manner, the series of 1,4-butanediol (99%, Sigma), 1,2,6-hexanetriol (96%, Sigma), pentaerythritol (>99%, Sigma), xylitol. Plasticizers and hydrogen bonding (FT-IR)

New oligoether plasticizers for poly(ethylene oxide)-based

Two new plasticizers, nitrile groups terminated oligoether (NOE) and lithium sulfonamide groups containing oligoether (LSA), have been synthesized to construct superior poly (ethylene oxide) (PEO)-based solid polymer electrolytes (SPEs). The chemical structures of these plasticizers were confirmed by FTIR, 1 H-NMR, and elemental analysis.

The plasticizers loss during service and storage leads to an abrupt decay of the mechanical properties (embrittlement) . The plasticizer migration however is also affected by the plasticizer molecular weight; in fact, higher is the plasticizer molecular weight, higher will be the plasticizer retention in the polymer matrix .
