Figure 10.3 Mean molecular mass between chemical crosslinks and trapped chain entanglements Mc+e in a cured mixture of a poly(ethylene glycol) diacrylate (PEGDA) and 2-ethylhexyl acrylate (EHA) as a function of the EHA content [52]. Mc+e values were determined from (1/T2s)max and the plateau modulus (see Figure 10.2). A substantial difference in Mc+e value, as determined by these two methods at low crosslink density, is caused by the effect of network defects which decrease volume average network density determined by DMA (see Section 10.3). The molecular mass of PEGDA (Mn = 700 g/mol) is indicated by an arrow. The molecular mass of network chains in cured PEGDA is about three times smaller than that of the initial monomer. The molecular origin of this difference is discussed in Section 10.3...

The addition of a suitable amount of PC or a mixture of PC and EC to PEO-(LiX) does increase the room temperature conductivity of the electrolyte to >10" Scm but apparently with a significant reduction in its dimensional stability. This limitation, coming from the fact that PEO is soluble in PC or in a mixture of PC and EC, can be overcome with the use of polymers which are insoluble in the plasticizing solvents. Examples of such materials are the series of dimensionally stable polymer electrolyte films with conductivities of >10" Scm at room temperature we have prepared [33, 34]. A list of these electrolytes and their conductivities at 20°C is given in Table 3.7. They are obtained by immobilizing solutions of Li salts (i.e. Li salt-solvates) formed in a mixture of ethylene carbonate and propylene carbonate, in a polymer matrix such as poly(acrylonitrile), (PAN), poly[(tetraethylene glycol) diacrylate] (PEGDA), and poly(vinyl pyrrolidinone), (PVP). These polymers are insoluble in PC and EC/PC mixtures consequently, dimensionally stable... [Pg.97]

Poly(methyl acrylate) (PMA) may be used as start material for production of shape-memory material [lOWl]. The addition of poly(ethylene glycol) diacrylate (PEGDA) assists crosslinking process. The insoluble content formed in EB-irradiated PMA increases sharply even at low doses (Table 37) because polymer matrix provides radicals at a yield of 0.77 and PEGDA plays the role of sensitizer. [Pg.209]

Other bio-responsive hydrogels have been developed to give an optical output that use different actuation methods. These include sensors for a-cyclodextrin, in which a reaction with polydiacetylene liposomes embedded in poly(ethylene glycol) diacrylate (PEGDA) leads to a visible colour change of the hydrogel from blue to red [17]. [Pg.50]
