    Abstract: In accordance with one embodiment, a polymer composite comprises a filler and a matrix. The filler comprises an electrospun polymer mat. The matrix comprises a polymer film. The filler is arranged to respond to stimuli by altering its mechanical properties. In one example, the mat can be electrospun from poly(vinyl alcohol), and the matrix can be formed from ethylene oxide-epichlorohydrin 1:1 copolymer. The filler can be arranged so that the tensile storage modulus of the polymer composite changes in response to the filler being exposed to a stimulus. In another example, the filler is about four percent by weight of the polymer composite.

  • Publication number: 20130065467
    Abstract: A substrate has a surface printed with an ink or coating composition with excellent adhesion and dry rub resistance, and very good oil and saline rub resistance (crock) properties using a multi-functional carbodiimide as a crosslinker for nonwoven substrates. The rub performance of the ink or coating printed on a nonwoven substrate has been found to be superior to that of a first Sun benchmark ink including pigments for four color printing. In another embodiment, a carbodiimide crosslinker such as multifunctional Carbodilite SV-02 is added to the compositions to further improve rub resistance (crock) and retain liquid characteristics post inoculation when compared to compositions using aziridine as a crosslinker. In a further embodiment, a thin polyolefin film exemplifying a backsheet of a hygiene product was printed with the same crosslinked ink or coating composition and compared with a second Sun benchmark set of inks.
