“It’s difficult to make predictions, especially about the future.” Various versions of this quote have been attributed to Niels Bohr, Mark Twain, Yogi Berra, Nostradamus, and many others. With resp...

The aging of a commercial filled siloxane polymeric composite in states of high stress and Co-60 γ-radiation exposure has been studied. DC-745 is a commercially available silicone elastomer consisting of dimethyl, methyl-phenyl, and vinyl-methyl sil

Crystallization in a series of variable crosslink density poly(dimethyldiphenyl)siloxanes random block copolymers reinforced through a mixture of precipitated and fumed silica fillers has been studied by differential scanning calorimetry (DSC), dynam

The effect of chemisorbed and physisorbed water on the interfacial structure and dynamics in silica-filled polydimethylsiloxane (PDMS) based composites have been investigated. Toward this end, we have combined molecular dynamics simulations and exper

We have measured changes in 1H NMR residual dipolar couplings, 〈Ω d 2 〉 , and the mean squared fluctuations in the residual dipolar couplings, 〈 δ Ω d 2 〉 , associated with cross-link density changes in a complex silica-filled PDPS/PDMS bl

We report 1 H and 13 C NMR analysis of changes in chain dynamics in a polyurethane elastomer system, Halthane 88-3, caused by exposure to 1.2 MeV gamma radiation from a Co-60 source. 1 H NMR relaxation measurements clearly discriminate between interf

Degradation mechanisms for complex polymer systems are often subtle and difficult to detect, yet a precise understanding of their effect on a polymer component's macroscopic performance is necessary for understanding aging behavior. Furthermore, pred

We have measured changes in transverse relaxation times (T2e), residual dipolar couplings (〈Ωd2〉), and the mean-squared fluctuations in the residual dipolar couplings (〈δΩd2〉), associated with cross-link density changes in a complex silica
