“…Where γ is the surface tension of the test liquid, θ is the contact angle between the test liquid and the polymer matrix, γ l d and γ l p are the dispersion force component and polar force component of the surface tension of the test liquid, respectively; and γ s d and γ s p are the dispersion force component and polar force component of the surface tension of the polymer solid, respectively. In this work, the surface tension ( γ )/dispersion force component ( γ l d )/polar force component ( γ l p ) of H 2 O and CH 2 I 2 are 72.8/22.1/50.7 mN/m and 50.8/44.1/6.7 mN/m, respectively 45 …”

Emulsion polymerization was used to create composites of polyaniline‐amino‐carbon nanotubes (PANI‐A‐CNT). Fourier transform infrared spectroscopy (FT‐IR) was used to examine the chemical bonding properties of PANI and carbon nanotubes in composite materials. Transmission electron microscopy (TEM) was used to confirm that the PANI layer on the core‐shell structure of PANI‐A‐CNT material was nanoscale in size. In order to assess the impact of various carbon nanotube contents on the electrostatic and mechanical properties of the composites, pristine carbon nanotube/ABS (p‐CNT/ABS) and PANI‐A‐CNT/ABS composites were prepared. The mass fractions of PANI and CNT in PANI‐A‐CNT were 93.7 and 6.3 wt%, respectively, according to thermogravimetric analysis (TGA); hence, 4 wt% of PANI‐A‐CNT included 0.3 wt% CNT and 3.7 wt% PANI. The surface resistance test revealed that the PANI‐A‐CNT/ABS composite with 4 wt% PANI‐A‐CNT has a surface resistance of 108 Ω, which is one time less than the surface resistance of the p‐CNT/ABS composite with 4 wt% p‐CNT. Moreover, PANI‐A‐CNT/ABS composite (0–4 wt% PANI‐A‐CNT) has stronger tensile and impact properties than p‐CNT/ABS composite (0–4 wt% p‐CNT), expanding the range of applications for ABS resin.

“…With the development of material modification research, many polymer materials possess serval unique properties, so the practical application fields of polymers in industry and life have been further expanded. For example, polymer materials can break through the traditional concept of insulation and explore its application in conductivity, such as wearable electronics, flexible electronics, and antistatic and electromagnetic interference shielding materials, [1][2][3][4][5][6][7] owing to their low cost, easy operation, and superior thermal properties. [8][9][10][11][12] The most frequent method used to fabricate conductive polymer composites (CPCs) is introducing the conductive fillers into various polymeric matrices, whether the matrix and fillers contain a single component or multiple components.…”

Conductive polymer composites (CPCs) are promising alternatives to metal conductive materials due to their light-weight and low-cost. This work investigates the effect of the crystallization behavior of the matrix on the electrical property of CPCs, where semi-crystalline polypropylene (PP) and amorphous styrene-butadiene-styrene tri-block copolymer (SBS) are selected as a matrix, respectively, and conductive carbon black (CB) particles are introduced into matrixes by melting blending. Based on the electrical properties of CPCs with various CB contents and percolation theory, the percolation threshold of 1.8 vol% in PP matrix composites is obtained, much lower than that of SBS matrix composites (5.4 vol%). The analysis with a polarizing microscope and differential scanning calorimeter confirms that such a significant difference in percolation threshold between two composites is due to the crystallization behavior while the crystallization induced segregated structure is proposed. Finally, the rheology behaviors and mechanical properties are characterized for microstructures and applications, respectively.

Solar thermal evaporation has been widely used to tackle the problem of freshwater shortage. The strategy to improve the evaporative performance of solar thermal evaporation by simple and effective methods is still a challenge. Herein, a dendritic structure-inspired coating strategy based on the dendritic structure of polyvinyl alcohol (PVA) colloids firmly grabbing titanium trioxide (Ti2O3) on the outer surface as a light-absorbing core–shell filler was prepared using the non-solvo-induced precipitation method. Such a core–shell structure was then coated on the PVA sponge to prepare the solar photothermal composite Ti2O3/PVA@PVA, which gave full play to the photothermal advantage of the filler itself and can be long-term stable. Meanwhile, a three-dimensional Ti2O3/PVA@PVA evaporator with an embossment-sawtooth structure was prepared, which enhances light absorption to 98% in the whole solar spectrum through folds. Under 1.0 solar irradiation, the evaporation rate reaches as high as 2.66 kg m–2 h–1 and the evaporator illustrates good stability in simulated seawater for 7 consecutive days. Such a design showed good salt resistance and self-cleaning ability and could be reliably used for seawater desalination. In addition, the evaporator illustrates good adsorption capacity for dye molecules and heavy metal ions. This work provides new insights into the development of simple, efficient, environmentally friendly, sustainable, and salt-resistant solar evaporators.
