摘要

We report a simple and environmentally friendly approach for preparing a homogeneous dispersion of poly(2-ethylhexyl acrylate)-silicon dioxide (P2EHA-SiO2) composites by self-assembly of negatively charged P2EHA and charged SiO2. The P2EHA latex particles were prepared by miniemulsion polymerization using a free-radical initiator. As auxiliary monomer, acrylic acid created the positive charges on the surface of the P2EHA latex. By mixing P2EHA latex particles with positively charged SiO2 (pSiO(2)) particles, negatively charged P2EHA latex particles easily assembled with pSiO(2) particles through electrostatic interactions. The presence of P2EHA latex particles assisted the homogeneous dispersion of pSiO(2) particles in the polymer matrix. After film formation process, the film exhibited excellent thermal-tolerance and adhesive properties. A three-component system of P2EHA latex particles, pSiO(2), and negatively charged SiO2 (nSiO(2)) was also achieved successfully due to the mutual assistance effect. A better thermal-tolerance and adhesive properties were obtained. Through the establishment of the film formation mechanism, we found that the architecture of the composite film has a significant influence on thermal-tolerance and adhesive properties. This composite material has great application potential as a PSA (pressure sensitive adhesive). Our research demonstrates an excellent composite system and provides a convenient approach to realize a wide range of multifunctional fillers, compatible with processing on flexible polymer substrates.
