The mechanics of nanocomposites is critical in the design of nanomaterials with desirable properties. In this paper, the mechanics of polymer−clay nanocomposites is studied using a designed polymer and solution nanocomposite synthesis. A copolymer

In-situ polymerization of silicon alkoxide was used to prepare composites of silicon dioxide and poly(vinyl acetate) (PVAc). The FTIR, dielectric, and dynamic mechanical spectroscopy results showed that β decreased with increasing sol-gel concentrat

The interfacial chemistry between evaporated Ag and poly(p‐phenylene sulfide) (PPS) has been investigated with x‐ray photoelectron spectroscopy (XPS). The initial stages of nucleation and growth of Ag in the subatomic‐layer regime were monitore

The nature of mixing in bimodal polystyrene homopolymer blends has been investigated by using small-angle neutron scattering. Blends were made from deuterated high (M ≈ 110 000) and hydrogenous low (M ≈ 1000–3000) molecular weight fractions. Th

The dielectric relaxation spectra of N,N′-bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine (PPB)-polycarbonate (PC) solid solutions have been studied as a function of composition. The glass transition of these mixed systems varies monotonically w

La cinetique de chloration est previsible jusqu'a une duree de reaction de 600 S au-dela de laquelle la reaction ralentit fortement en raison d'effets steriques. La spectroscopie XPS demontre l'existence d'une distribution temporelle des especes mono

The dielectric behavior of poly(diethyl siloxane) supports the adiabatic calorimetric findings of Beatty and Karasz. In particular, a sub-Tg transition is observed near −180°C at 100 Hz, the glass transition near −135°C at 100 Hz, and a first-o

Gas-phase derivatization has been used along with e.s.c.a. to determine corona-discharge-induced chemical species on poly(ethylene terephthalate) (PET). Dry-air and dry-nitrogen coronas were studied. We showed that: (1) if the corona discharge treatm
