“…Since the TMQ was soluble in water, some of the TMQ distributed on the surface would be carried away by water during the washing process, which made the water film formed on the surface be destroyed and led to an increase in the surface resistivity. However, TMQ is a polymer, not a small molecule, it was difficult to elute from the PP matrix, 34 leading to the surface resistivity increase but a slow trend.…”

“…The TMQ migrated to the surface would adsorb more water, which promoted the ionization of it and reduced the surface resistivity. Meanwhile, TMQ is a macromolecule that cannot migrate as fast as small molecules 34 . This allowed the TMQ to migrate outward slowly and not be easily dislodged, and its surface resistivity remained essentially unchanged over a long period of time.…”

“…This implied that TMQ had a role in promoting the crystallization of PP. However, the molecular chain of TMQ was too long to move, 34 and the effect of hindering the crystallization of PP was greater than that of promoting it.…”

In this paper, a novel polymeric antistatic agent, TMQ, with excellent antistatic properties, low cost, and good compatibility with polypropylene (PP), was prepared from isopentenyl polyoxyethylene ether (TPEG), maleic anhydride (MAH) and homemade quaternary ammonium salt (QAS). The structure is characterized using FTIR and 1H NMR. How the addition of TMQ and the molar ratio of TPEG, QAS, and MAH affect the antistatic, mechanical, and crystalline properties of PP are investigated. The results show that as the feed ratio of TPEG, MAH and QAS is TPEG:MAH:QAS = 1:8:8, the modified PP displays the best overall performances. Further exploring finds out when TMQ is added at 15 wt%, the surface resistivity of PP reduces to 6.78 × 109 Ω/sq and the volume resistivity of PP reduces to 7.9 × 109 Ω cm−1, the notched impact strength and melt index improve by 357% and 991%, respectively, while the tensile strength decreases by 38.6% compared with that of pure PP. Besides, the crystal study shows after TMQ is added, the crystallinity of PP reduces, the melt peak temperature remains essentially unchanged, and the crystallization peak temperature increases slightly. The material has excellent antistatic resistance to washing and durability, and the changes in relative humidity have little effect on its antistatic properties.

“…Future work could concern itself with optimizing the generation and dispersion of HPV, a method for measuring the signal, electronic models, device architecture, a composite material system to inhibit the polymer from swelling under humid conditions, and the films’ optic/electronic performances. PEDOT:PSS is highly tunable [ 8 , 40 , 41 ]. Optimization studies could begin by employing secondary dopants such as the volatile organic reagents dimethyl sulfoxide (DMSO) and ethylene glycol (EG) to enhance the sensitivity of the response by substantially increasing the films’ initial conductivity, or constructing covalent crosslinking systems with polyvinyl alcohol (PVA) and glutaraldehyde (GA) to improve the films’ stability and immunity to interference under varying levels of humidity.…”

Hydrogen peroxide (H2O2) is commonly used as an oxidizing, bleaching, or antiseptic agent. It is also hazardous at increased concentrations. It is therefore crucial to monitor the presence and concentration of H2O2, particularly in the vapor phase. However, it remains a challenge for many state-of-the-art chemical sensors (e.g., metal oxides) to detect hydrogen peroxide vapor (HPV) because of the interference of moisture in the form of humidity. Moisture, in the form of humidity, is guaranteed to be present in HPV to some extent. To meet this challenge, herein, we report a novel composite material based on poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) doped with ammonium titanyl oxalate (ATO). This material can be fabricated as a thin film on electrode substrates for use in chemiresistive sensing of HPV. The adsorbed H2O2 will react with ATO, causing a colorimetric response in the material body. Combining colorimetric and chemiresistive responses resulted in a more reliable dual-function sensing method that improved the selectivity and sensitivity. Moreover, the composite film of PEDOT:PSS-ATO could be coated with a layer of pure PEDOT via in situ electrochemical synthesis. The pure PEDOT layer was hydrophobic, shielding the sensor material underneath from coming into contact with moisture. This was shown to mitigate the interference of humidity when detecting H2O2. A combination of these material properties makes the double-layer composite film, namely PEDOT:PSS-ATO/PEDOT, an ideal sensor platform for the detection of HPV. For example, upon a 9 min exposure to HPV at a concentration of 1.9 ppm, the electrical resistance of the film increased threefold, surpassing the bounds of the safety threshold. Meanwhile, the colorimetric response observed was 2.55 (defined as the color change ratio), a ratio at which the color change could be easily seen by the naked eye and quantified. We expect that this reported dual-mode sensor will find extensive practical applications in the fields of health and security with real-time, onsite monitoring of HPV.

Developing epoxy structural adhesives with excellent high‐temperature adhesion remains a great challenge. The incorporation of fillers can enhance the performance of epoxy adhesives, albeit at the expense of reduced high‐temperature adhesion properties. Polyhedral oligomeric silsesquioxanes (POSS) is considered a promising filler for enhancing high‐temperature adhesion properties due to its excellent compatibility and nano cage‐structured. Herein, the rigid cage‐structured was covalently introduced epoxy adhesives to improve the high‐temperature adhesion properties. The introduction of 1 wt% POSS significantly increased the high‐temperature (120°C) adhesion strength by 197% and toughness by 283%. The POSS‐reinforced adhesive also featured excellent wide temperature adaptability, indicating that it maintained high adhesion strength at various temperatures. Furthermore, POSS drastically enhanced the transparency of epoxy adhesive by three times. It is highly anticipated that this work will open a new avenue of designing epoxy adhesives with the excellent high‐temperature adhesion properties and transparency.
