With the technological developments witnessed in recent decades, nanotechnology and nanomaterials have found uses in several common applications and products we encounter daily. On the other hand, polyurethane (PU) foams represent an extremely versatile material, being widely recognized for their extensive application possibilities and possessing a multitude of fundamental attributes that enhance their broad usability across various application fields. By combining the versatility of PU with the antimicrobial properties of nanoparticles, this emerging field holds promise for addressing the urgent need for effective antimicrobial materials in various applications. In this comprehensive review, we explore the synthesis methods, properties and applications of these nanocomposite materials, shedding light on their potential role in safeguarding public health and environmental sustainability. The main focus is on PU foams containing metal and metal oxide nanoparticles, but a brief presentation of the progress documented in the last few years regarding other antimicrobial nanomaterials incorporated into such foams is also given within this review in order to obtain a larger image of the possibilities to develop improved PU foams.

“…The basic building block of PU is the carbamate group, which is formed through the additional polymerization of isocyanates with diols or polyols . Owing to their excellent wear resistance, toughness, mechanical strength, corrosion resistance, and processability, − they are widely employed in various fields, including coatings, , adhesives, , fibers, , thermoplastics, , thermosetting materials, , biomimetic materials, , and nanocomposites. , Commonly used polyisocyanates include aromatic and aliphatic isocyanates, such as toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), and hexamethylene diisocyanate (HDI), which are derived from fossil feedstocks. − However, with the increasing global demand for PU, traditional polyisocyanates are facing challenges caused by decreasing fossil resources and increasing environmental pollution. New biobased isocyanates have attracted widespread attention from researchers and industries because of their high biochar content.…”

New biobased pentamethylene diisocyanate (PDI) trimers have received increasing attention because of their high biochar content and excellent performance in coatings. However, their viscosity can affect the curing rate and application of coatings. This study aimed to decrease the viscosity of PDI trimers by reducing the content of high-molecular-weight oligomers. Using 2-hydroxypropyltrimethylisooctanoic acid ammonium salt as a catalyst at a dosage of 0.3 wt ‰, the catalyst was added in two batches at 80 °C, with an interval of 15 min between each addition. The reaction lasted for 90 min until the NCO conversion rate reached 15.71%. The resulting PDI trimer contained a high-molecular-weight oligomer content of 0.53% and exhibited a viscosity of 1425 mPa·s. Furthermore, to address the significant increase in the content of high-molecular-weight oligomers during the later stages of the reaction, a novel reaction pathway was proposed to elucidate the generation of high-molecular-weight oligomers from those with lower molecular weights. Gaussian calculations were employed to determine the reaction energy barriers of different pathways, confirming that the reaction pathway for synthesizing a heptamer from two trimers and one monomer is possible. Moreover, this study provides insights into methods for mitigating the increase in high-molecular-weight oligomers in the later stages of the reaction.
