“…The balance of mechanical strength, toughness, and bonding strength is the key to elastomers as laminated glass intermediate films. Some methods have been developed in response to these problems. − For example, a simple and effective method to obtain modified TPU films by silane coupling agent (SCA) treatment was reported . Hydrogen bonds were formed between the silicon hydroxyl groups generated by the hydrolysis of the SCA.…”

In recent years, safety laminated glasses have been widely used in construction, transportation, military, and other fields owing to their safety, comfort, and concealment. In this work, a cellulose nanocrystal was synthesized and blended in a polyurethane (PU) elastomer. Based on this, an aliphatic PU composite (CPU) film with high transparency and excellent mechanical properties has been achieved by stepwise polymerization. The mechanical properties and impact resistance of CPU composites were improved obviously, attributed to the microphase separation and hydrogen bonding. The tensile strength and bonding strength of the CPU film with glass can reach 53 and 3.4 MPa, which were 150 and 280% higher than those of the PU film, respectively. Extremely strong impact resistance of the laminated glass based on the CPU film has been confirmed by the falling ball impact test, which was 2.3 times that of polyvinyl butyral and 3.5 times that of PU. It will be an excellent candidate for safety laminated glass, which can be used in the aerospace, defense, and automotive fields.

Thermoplastic polyurethane (TPU) has been applied to high‐performance laminated glass depending on its high impact strength and bonding properties. The utilization of various polyurethane molecular structures in laminated glass is scarcely reported. The selection and application of chain extenders are crucial for TPU performance. In this work, aliphatic polyurethane film with high strength has been successfully synthesized, incorporating chain extender of poly(propylene glycol) bis(2‐aminopropyl ether) (PEA230). The films with melting point above 80°C were prepared by adjusting the proportion of dimethylglyoxime (DMG), while simultaneously monitoring the thermal behavior of the samples by DMA. Results indicate that combining PEA230 and DMG in a 1:1 molar ratio yields the hydrogen bonding degree of 85.77%, toughness of 43.14 MJ m3, and shear stress of 1.8 MPa for the polyurethane film. Subsequently, laminated glasses based on the polyurethane film with different thermal properties were constructed successfully, and their super strong impact resistance was confirmed through falling ball impact experiments.

As the construction industry places increasing emphasis on environmental conservation and sustainability, this trend has spurred profound research into the optimization of door and window performance. One of the critical components of windows is their frames. Over the past several decades, the design of window frames has undergone significant innovations, ranging from introducing new materials to novel design concepts. The performance of window frames is typically influenced by materials, structural design, and the surrounding environment. Consequently, this paper analyzes the common window frame materials in Chinese civil buildings through investigation. It explores commonly used types of window frames available in the market, focusing on their materials and structural designs. It analyzes issues observed during their usage, integrates findings from existing research, and discusses the performance of window frame materials. Additionally, it explores improvement strategies to meet the evolving demands of contemporary and future architectural doors and windows, providing valuable reference points for designers. Finally, approaching the discussion from a sustainable development perspective, the paper evaluates the environmental impact of wood, aluminum alloy, polymer, and composite window frame materials. It emphasizes that wood- and aluminum-clad wood windows represent sustainable options with versatile applications in diverse scenarios.
