A green and facile fabrication strategy for synthesis of lignosulfonate-graphene porous hydrogel (LGPH) was designed via incorporation of lignosulfonate (LS) into graphene oxide (GO). This process was achieved by a simple self-assembly method at low temperature, with LS serving as surface functionalization agent. Benefiting from the abundant functional groups of LS and the large surface areas of graphene oxide, the prepared LGPH hydrogel displayed 3D interconnected pores and exhibited an excellent adsorption capacity for Cr(VI) (601.2 mg/g) ions dissolved in water. Importantly, the free-standing LGPH was easily separated from water after the adsorption process, and the adsorption capacities of Cr(VI) onto LGPH maintained 439.1 mg/g after 5 adsorption-desorption cycles. The cost-effectiveness and environmental friendliness of LGPH make it a promising material for removing heavy metals from wastewater.

As an energy-efficient surface modification method, self-assembly has been the subject of extensive research. However, its application on carbon film has been rarely reported. In the present work, a novel self-assembled reduced graphene oxide (RGO) was prepared on a-C:H film by a controllable self-assembly method, and the friction behavior of the RGO/a-C:H film was investigated under vacuum environment. Interestingly, the RGO/a-C:H film exhibited significant improvement of anti-wear ability in vacuum conditions under a high applied load of 5 N. As expected, the synergy lubrication effect of the RGO layer and a-C:H film should account for the excellent friction reduction and anti-wear ability of a RGO/a-C:H multilayer film.

Purpose – The purpose of this paper is to create a textile material which shows antibacterial activity with resistance to environmental conditions by using volatile active agent inclusion complex and self-assembly method. Design/methodology/approach – An inclusion complex of carvacrol and β-CD is generated by kneading method and deposited on the cotton fabrics by using a nanofabrication method named as layer-by-layer (LbL) deposition method. Three different concentration of CD and CD:Car aqueous solutions were deposited on cotton fabrics. Attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), antimicrobial efficacy test of fabrics against washing and some physical tests (water vapor permeability, air permeability) were performed on the fabrics before and after the treatment with CD to evaluate the effect of the LbL process on cotton fabric properties. Findings – The results showed that the coated fabrics with CD/CD:Car multilayer films enhanced the antimicrobial efficacy of cotton fabrics against to Klebsiella pneumonia and Staphylococus aureus bacteria. Air and water vapor permeability properties of the cotton fabric effected after the LbL deposition process sure enough. With SEM and FTIR-ATR analysis the CD:Car complex presence were verified. The durability of antibacterial properties were analyzed after one and ten washing (40°C and 30 min) cycles. Originality/value – This work provides a novel and simple method for CD and inclusion complex of carvacrol film deposition by self-assembly method on cotton fabrics and their application onto cotton fabrics to gain antibacterial property.
