Dawn A. Bonnell Ferroelectric Organic Materials Catch Up with Oxides-science-2013 An organic salt displays ferroelectric properties comparable to those of barium titanate but should be easier to process in device fabrication. This combination of ferroelectric phase stability and outstanding properties suggests that DIPAB may replace oxides in some applications, with benefi ts in terms of ease of processing and sustainability. Further, the surprisingly strong ferroelectric behavior in this organic compound suggests a reconsideration of the generality of charge interactions that underlie related properties. Other properties, notably piezoelectricity and electrostriction, are manifestations of charge interactions in structures and are well known in solids. Recently, evidence of all three of these properties has been observed on local scales in components of biological or physiological materials , so perhaps ferroelectric coupling is an important part of some biological processes. In that case, the highly functional DIPAB may be the bridge in understanding between coupling in oxides and that in complex soft materials.[ Last edited by wiseroy on 2014-3-4 at 09:28 ] |
