General Properties
Piezotech FC TM is a range of P(视频高清版VDF-TrFE) copolymers of various 中文版大地compositions. Piezotech FC TM Polymers are:
成全好姑娘;Piezoelectric: these polymers convert mechanical into electr好姑娘丁香花ical energy and inversely, these materi影院国语als have high mechanical strength, higTV美丽h stability to chemicals, oxidants, ultra高清版美丽violet and low acoustic impedance免费成全 (close to water or human tissues).
Pyroelectric: these polymers convert calorific en免费好姑娘ergy into electrical energy an inversely. Polymer影院好姑娘 films absorb in the 6-20µm wave直播国语length range.
Applications printed keyboards, sensors, 艺术大地energy harvesting, transducers, speakers, microp国语影院hones, FeFET, ferroelectric memories, IR or fing高清好姑娘ertips detectors…

Solubilization & Filtration
Piezotech RT TM polymers are so成全MVluble in ketone solvents (Methy高清版中文版l Ethyl Ketone (MEK), Methyl Isobutyl Ketone动漫美丽 (MIBK), cyclo-hexanone, cylopentanone etc…), Di免费好姑娘methyl formamide (DMF), Dimethyl Sulfoxide (DMSO)影院视频, Phosphate solvents (Triethyl phosphate) 大地姑娘etc… In order to get homogeneous films 姐姐在线with high electrical breakdown a filter丁香花好姑娘ing step of the solution is require影院大地d, it will remove impurities and preveGO成全nt gel formation.

Film Formation
Solution can be deposited via solvent cas免费在线t, screen printing or spin-coa姐姐在线ting or other printing technique飘雪姑娘s on a glass, silicon, Polyimide, PEN…好姑娘GO substrate under clean atmospherTVGOe until an homogeneous and dry film is formed.

Film annealing
Annealing is a critical step to provide film wit美丽影院h the best properties, it will control crystal艺术姐姐lization of the material and enhance eGO直播lectrical as well as mechanical proper中文版美丽ties. Rapid annealing may be obtained GO高清版on thin films using Infrared or Flash anneal大地飘雪ing.

Film and deposition poling
To activate a copolymer material, a po中文版好姑娘ling step is necessary. An electric f飘雪好姑娘ield above the coercive field 丁香花在线value (ie 50V/µm) and ty好姑娘直播pically twice the coercive field va直播成全lue has to be applied. For thin layers姐姐国语 of printed devices, electric field can be飘雪高清版 applied directly through the devi好姑娘艺术ce’s electrodes. For thicker films, polin直播好姑娘g can be done trough contacting an高清直播d pressing the film between el免费飘雪ectrodes and applying an increasing low frequencyTV免费 voltage. For large surface, o免费GOne can use corona poling.
Clean-up
The product can be cleaned up with ketones丁香花成全 solvents (MEK (methyl ethyl ketone)视频高清版, Cyclopentanone …)
