Abstract Lignin is a natural macromolecular sun blocker and provides an ideal protection material for pesticides that have poor photostability. In this study, alkali lignin/prochloraz capsules (AL-P) were prepared via one-pot ultrasonic cavitation. The results demonstrated that the produced AL-P were uniform spheres with sizes of 170–375 nm. The prochloraz encapsulation efficiency (EE) and loading capacity (LC) reached as high as 91.8 and 98.5%, respectively. Adding a small of surfactant reduced the size of the capsules, but both EE and LC were decreased. AL-P exhibited excellent extended release performance. The cumulative release of AL-P in the first 45 h was 76.1% and continuous release was maintained after 96 h. The resulting AL-P have improved photostability under UV irradiation radiation. Finally, AL-P capsules were sprayed on the mango leaves and bananas to act as preservatives, AL-P capsules had stronger rain wash resistance and were better preserved demonstrating their industrial applicability. Together, organic solvent free AL-P capsules demonstrate a method to improve the efficiency of photosensitive pesticides.

Synthesis of photoreactive solvent-free acrylic pressure-sensitive adhesives in the recovered system The present paper discloses a novel photoreactive solvent-free acrylic pressure-sensitive adhesive (PSA) systems, especially suitable for the so much adhesive film applications as the double-sided, single-sided or carrier-free technical tapes, self-adhesive labels, protective films, marking and sign films and wide range of medical products. The novel photoreactive solvent-free pressure-sensitive adhesives contain no volatile organic compounds (residue monomers or organic solvent) and comply with the environment and legislation. The synthesis of this new type of acrylic PSA is conducted in common practice by solvent polymerisation. After the organic solvent are removed, there remains a non-volatile, solvent-free highly viscous material, which can be processed on a hot-melt coating machine at the temperatures of about 100 to 140°C.
