Second harmonic generation (SHG) was used to measure the temperature dependence of the reorientation activation volume (ΔV*) of a syndioregic main-chain hydrazone (SMCH) nonlinear optical polymer. The decay of the SHG signal from poled films of SMCH

Fully atomistic molecular modeling is performed on an electric field poled guest-host nonlinear optical polymer system at two different densities. The higher density (HD) represents a sub-Tg system, while the lower density (LD) corresponds to a syste

A recent rotational isomeric state (RIS) model for a polybenzoxazine (PBO) was used for generation of a fully atomistic model for the amorphous material at its bulk density of 1.1 g cm−3. The initial structure was relaxed by a combination of molecu

The diffusion of water and oxygen molecules in the polybenzoxazine (PBO) matrix was studied at 295 and 450 K using fully atomistic molecular modeling. The hydrogen bonding of water and the hydroxyl groups in PBO is evident in the pair correlation fun

A Rotational Isomeric State (RIS) model has been constructed for the polybenzoxazine with a repeating unit of [−C 6 H 2 (OH)(CH 3 )–CH 2 –N(CH 3 )–CH 2 −], with the four nonhydrogen substituents bonded to the aromatic ring arranged with the

Atomistic polybenzoxazine (PBO) thin films of thickness ∼28 A were constructed in a vacuum from the bulk amorphous PBO by increasing one edge (the z-axis) of the cubic cell enough, 100 A, so that the atoms cannot interact with periodic images in th
