Abstract
Thin flexible mats of IPN-Multiferroic perovskite were prepared using In-situ polymerization of PU/PMMA & (PrFeO3)0.24-(PbTiO3)0.76). X-ray diffraction peaks confirmed the presence of a tetragonal crystal phase (P4mm No. 99) of perovskite in a non-crystalline interpenetrating polymer network (IPN). The M-H hysteresis revealed the presence of magnetic ordering, whereas the P vs. E loop showed the presence of ferroelectric ordering in composites. The detection of elements present in the sample was done by energy-dispersive X-ray spectroscopy (EDS). The FTIR spectra of flexible mats revealed distinct transmittance peaks indicating various functional groups, including Si-OH, OH, methylene (CH2), urethane carbonyl (C=O), Si-O-Si, Fe-O, Ti-O, and PbO, thus, confirming their expected presence within the sample. The variation in weight loss and elongation at the break due to the incorporation of multiferroic ceramic directly manifested improved mechanical properties of pure IPN. The change in voltage with both frequency and magnetic field, attested for magneto-electric coupling in the prepared flexible sheets. We also observed the magnetoelectric coupling coefficient ‘αME’ by subjecting the sample to an AC magnetic field of 20 Oe, scanning frequencies from 150 Hz to 500Hz. The maximum value of ‘αME’ was obtained between 180 Hz and 220 Hz. At three different frequencies (180 Hz, 200 Hz, and 220 Hz), the DC magnetic field varied from 0 to 10.31 kOe. The maximum ME coefficient, 1.66 mVcm-1Oe-1, is obtained for x = 40 wt%. This predicts their capability to be used in various device applications including magnetic field sensors.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
