Formation process of flax fiber reinforced biocomposites based on waterborne matrix systems from modified polymers - polyhydroxybutyrate, poly (vinyl alcohol) was developed by suspension casting technique. Two kind of flax fiber as reinforcement was employed Latvian variety Vega-2 and flax combing. The correlation between matrix composition, fiber origin, content and mechanical characteristics, water vapour absorption and biodegradability was established. Optimal characteristics of elaborated eco-composites were obtained by use of flax combing with fiber content ~ 30 wt. %.

Sulfonated endcapped poly (arylenethioethersulfone) copolymer (SPTES) was synthesized through direct copolymerization of sulfonated monomers and poly (vinyl alcohol) (PVA) was crosslinked with SPTES by the dehydration method. The mechanical characteristics of polymer actuators are investigated. Nafion actuators as a comparison were also investigated. The normalized tip displacements were calculated for both PVA/SPTES actuators and Nafion actuators in order to delete the dimensions influence on the bending behaviours. The bending performances were tested under AC excitations with different frequencies. The results showed that the normalized tip displacement decreased with both the width and length of the IPMC strips. That is due to the increase of the monment inetia of the IPMC strips with the increment of the width or the length increment will lead to the larger resistance force from ambient water along with the increase of the area of IPMC strips. PVA/SPTES actuators showed comparable bending performances compared with its Nafion counterparts based on the study of mechanical properties.
