TL;DR: In this article, the tensile and flexural properties of iPP-EOC blends containing up to 20% EOC content were determined, and the impact strength of blend containing 5 % EOC increased drastically to the tune of 200% whereas the modulus and strength decreased marginally.
Abstract: Blends of isotactic polypropylene (iPP) and ethylene-octene-copolymer (EOC), having different proportions, were prepared in a co-rotating twin screw extruder The tensile and flexural properties of iPP-EOC blends containing up to 20% EOC content were determined Impact strength of blend containing 5% EOC increased drastically to the tune of >200% whereas the modulus and strength decreased marginally The effect of EOC content on the mechanical properties was found to be linear suggesting uniform dispersion of EOC domains in polymer matrix Various proportions of treated sisal and banana fibers were blended with iPP-EOC blend containing 5% EOC polymer matrix by melt blending technique Both tensile and flexural properties increased whereas impact strength decreased with increase in fiber content The extent of reinforcing effect of both sisal and banana fiber on iPP-EOC matrix is at comparable level The melting point of composites was lower than virgin iPP, and the degree of crystallinity of composites wa

TL;DR: In this paper, a preparation method of chemically modified sisal hemp carbon fiber photocatalyst is presented, which is simple in technology, low in cost, and applicable to industrial production.
Abstract: The invention relates to the field of catalytic materials for waste water treatment, and discloses a preparation method of a sisal hemp carbon fiber photocatalyst. The preparation method comprises the following steps: firstly, calcinating sisal hemp into porous carbon fiber with strong adsorption effect, and loading titanium dioxide nanoparticles and molybdenum disulfide quantum dots onto porous carbon by adopting a sol-gel method to obtain a tri-compounded porous carbon material. Through the photocatalyst, not only can the energy gap of titanium dioxide be reduced, but also the transfer efficiency of electrons can be enhanced, the visible light response range of the catalyst can be extended, and the modified titanium dioxide photocatalyst has response to visible light with wavelength of more than or equal to 460nm. According to the preparation method, the high-efficiency utilization of resources can be realized by fully utilizing natural sisal hemp, thus meeting green ecological concept. The preparation method of chemically modified sisal hemp carbon fiber photocatalyst is simple in technology, low in cost, and applicable to industrial production.

TL;DR: Inverse gas chromatography has been used to investigate changes to the surface of Sisal fibres on treatment with sodium hydroxide as discussed by the authors, finding that the major effect of the treatment was the removal of weak or adventitious layers from the substrate surface, thus increasing the interfacial shear strength when incorporated into polyester resin.
Abstract: Inverse gas chromatography, IGC, has been used to investigate changes to the surface of Sisal fibres on treatment with sodium hydroxide. By determining the retention of a series of alkane probes and of probes with acidic or basic character, it was shown that little change to the chemical nature of the surface occurs as measured by the enthalpy of adsorption of alkane probes or the dispersion component of the surface free energy. This IGC study supports the conclusion of previous work involving S.E.M. which suggested that the major effect of the treatment was the removal of weak or adventitious layers from the substrate surface, thus increasing the interfacial shear strength when incorporated into polyester resin.
