Abstract.
Reversible pH-sensitive polymers are polyelectrolytes that contain weak acidic or basic groups in their structure, which can either accept or release protons in response to changes in environmental pH.
The metacrylic acid ester structure of two monomers can imply the random sequence of two monomer units in copolymer chain.

ABSTRACT
After depositing amorphous (Bi0.5La0.5)(Ni0.5Ti0.5)O3 (BLNT) films on BLNT seed layer/Pt(100)/
MgO(100) substrates by room-temperature sputtering, the crystallization of the perovskite-struc-
tured films has been tried by hot isostatic pressing (HIP).
The samples with a single-phase perovskite structure HIP-treated at 800C for 1 h under gas pressures of 0.51.0 MPa showed good crystallinity of = 0.960.98 without accompanying the precipitation of the secondary phase.
However, as inferred from the decomposition reaction [6Bi(Ni0.5Ti0.5)O3 (BNT) Bi4Ti3O12 (BIT) + 3NiO + Bi2O3] in perovskite BNT compound, BNT under atmospheric conditions forms a stable bismuth layer structure and leads to the formation of BIT phase which is a typical compound of bismuth layer-structured ferroelectircs (BLSFs) [1,2].
For the samples without HIP treat- ment and HIP-treated at comparatively low tempera- ture of 700C, the crystallinity can hardly be con- firmed, whereas only the sample HIP-treated at 800C shows the single-phase perovskite structure.
(3) The perovskite-structured BLNT sample HIP-treated at 800C for 1 h under gas pressure of 1.0 MPa showed the best hysteresis loop shape with a remanent polarization of Pr = 5 C/cm 2 and a coercive field of Ec = 150 kV/cm of the six.

The devices based on EMA/ BMI copolymer possess a sandwich structure comprising bottom indiumtin oxide (ITO) electrode and top Ag electrode.
Furthermore, polymers devices can be easily incorporated into a high operating speed, high storage density, low power consumption and low fabricating cost structure of advanced memory devices, which are currently demanded for the storage of multimedia data [3~6] .
A wide variety of polymer materials have been explored, it is found that the electronic memory behavior is highly dependent on the chemicals structure of the materials, which dictates properties such as the occurrence of charge transfer(CT) conformation change and charge trapping among others.
The sandwich structure memory devices fabricated with EMA/BMI copolymer as the active layer exhibits the nonvolatile rewritable flash type memory characteristics.

The influences of annealing temperature on the crystal
structure of the films were analyzed by X-ray diffraction(XRD).
Notice that only (0 0 2h) reflections are observed, indicating that both are highly crystalline and oriented and layered perovskite structures have already been formed.
The as-deposited (C6H13NH3)2PbI4 film has an "amorphous" pattern, with no observable X-ray peaks, suggesting that the desired crystalline structure was not formed.
Above this temperature the films started to slowly decompose, presumably by the decomposition and loss of the organic component of the structure.

Their structures were characterized by XRD and FTIR analysis, and their photocatalytic performance was examined by decolorizing of two dyes and one real textile wastewater.
The composite photocatalysts were prepared by the sol-gel method, and their structures were characterized by XRD and FTIR.
It showed that the coated TiO2 did not greatly change the structure of diatomite, indicating the physical interaction between TiO2 and diatomite.
Their structures and photocatalytic activity were studied.
