BIOHARV project INTERREG V - Piezoelectric biobased polymers - Data set n°1

The BIOHARV projet is financed by FEDER, Wallonia Region, West-Vlaanderen Region and Agentshap Innoveren & Ondernemen. BIOHARV project started on 2016, October 1st for 4 years. Six academic & technological partners are gathered (Institute Mines Telecom North Europe, Armines, University of Mons, Centexbel, University of Lille and Polytechnic University Hauts-De-France. The main objective of the BIOHARV project is demonstrate & investigate piezoelectric, electroactive & electromechanical properties of biobased polymers. 

This dataset includes the evaluation of shear piezoelectric properties for various types of PLA processed by extrusion-MDO (machine-direction orientation) without high voltage poling. The technique used is based on a bimorph cantilver technique. The related article "Determination of Shear Piezoelectric Coefficients by a Bimorph Cantilever Technique for Extruded and Oriented Poly(L-Lactide) Films" will be published soon.

BIOHARV项目（BIOHARV）由欧洲区域发展基金（FEDER）、瓦隆大区（Wallonia Region）、西佛兰德斯大区（West-Vlaanderen Region）以及创新与企业署（Agentschap Innoveren & Ondernemen）资助。该项目于2016年10月1日启动，执行周期为4年。项目汇聚了6家学术与技术合作伙伴：北欧矿业电信学院（Institute Mines Telecom North Europe）、阿尔米内斯学院（Armines）、蒙斯大学（University of Mons）、Centexbel、里尔大学（University of Lille）以及上法兰西理工大学（Polytechnic University Hauts-De-France）。BIOHARV项目的核心目标是论证并研究生物基聚合物的压电、电活性及机电性能。

本数据集包含对经挤出-MDO（machine-direction orientation，纵向拉伸）工艺制备的各类聚乳酸（PLA）试样的剪切压电性能评估，且未经过高压极化处理。本次测试采用的技术基于双晶悬臂梁法。相关学术论文《Determination of Shear Piezoelectric Coefficients by a Bimorph Cantilever Technique for Extruded and Oriented Poly(L-Lactide) Films》即将发表。
