  In agricultural field, polymers are widely used for many applications. Although they were used, in the first time, just as structural materials (inhert polymers), in the last decades functionalized polymers revolutionized the agricultural and food industry with new tools for several applications. Smart polymeric materials and smart delivery systems helped the agricultural industryto combat viruses and other crop pathogens, functionalized polymers were used to increase the efficiency of pesticides and herbicides, allowing lower doses to be used and to indirectly protect the environment through filters or catalysts to reduce pollution and clean-up existing pollutants. This report will review the key aspects of used polymers in agricultural area, highlighting current research in this field and the future impacts they may have.

  The synthesis, characterisation, helical pitch and electro-optical response of new ferroelectric liquid crystals, 4’-(ω-acryloxyalkoxy)-, 4’-(ω-alkanoyloxyalkoxy)- or 4’-(ω-perfluoroalkanoyloxy)alkoxybiphenyl-4-yl (S)-4-(1-octyloxy)benzoates, bearing either polymerisable or non-polymerisable terminal groups, are described. The synthesised liquid crystals exhibit both a chiral smectic C phase and a chiral nematic phase. The helical pitch and electro-optical properties of the new compounds were determined as a function of temperature.
