  • Publication number: 20240093024
    Abstract: A polymer is formed by capping a copolymer-graft-polylactone with an alcohol, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The polymer can be mixed with an organic solvent and pigment powder to form a dispersion. The dispersion can be mixed with a binder to form a paint.

  • Publication number: 20190002177
    Abstract: A stretchable piezoelectric sensor applied to logistics for real-time monitoring includes a stretchable flexible substrate and a conductive layer formed on the flexible substrate. A plurality of sensing members corresponding in number to end faces of a packaging box is adhered to the conductive layer. When the piezoelectric sensor is placed at the bottom of the packaging box containing goods, two ends of the piezoelectric sensor can be stretched to fit on the diagonal corners of the packaging box, and the sensing members are located on the respective end faces of the packaging box to achieve an all-round monitoring.
