“…47 When these silica nanoparticles are used in cement paste without a superplasticizer, the mixture viscosity increases, and more air bubbles are introduced into the matrix, 48 which is detrimental to the porosity and permeability of the cement structure.

The oil well cementing job is the operation in which a cement paste is pumped to fill the annulus behind the casing. Inclusion of nanomaterials in oil well cement results in improving the cement properties. This paper provides a comprehensive overview of incorporating nanosilica into oil well cement, addressing various aspects of the nanosilica manufacturing process, dispersion challenges, the impact on cement hydration and properties, as well as the operational challenges. The addition of nanosilica is found to enhance cement properties such as hydration rate, compressive strength at low temperatures, and resistance to deterioration at high temperatures. However, challenges arise, including increased viscosity and the need for higher water content. Dispersion of nanosilica into cement slurry remains a difficulty, compounded by the high manufacturing cost, limiting its practical application. The paper recommends further research to improve nanosilica dispersion, explore cost-effective raw materials, and overcome operational challenges for broader utilization in oil well cementing.

“…This strategy not only introduces enhanced and complementary attributes but also unlocks new synergistic functionalities that remain elusive in isolated components 15–17 . Although contemporary core–shell structures typically feature inorganic nanoparticles as cores, such as silica core–shell nanoparticles, 18 titanium dioxide, 19 and magnetic core–shell nanoparticles, 20 their efficacy in bolstering toughness remains constrained. A typical example is that Douse et al 21 used core–shell rubber with siloxane as a core to modify polybezoxazine.…”

To further increasing the toughness performance of thermoset resins without sacrificing their other properties is still a challenge task. In this study, the soft core–soft shell nanoparticles based on polydopamine‐modified cellulose nanocrystals (P‐CNC) were synthesized and seamlessly integrated with Bisphenol A‐aniline benzoxazine (BA‐a). Notably, the results underscore the remarkable impact of a mere 0.2 wt% of P‐CNC on BA‐a, boosting the impact strength of the modified system to 19.5 kJ/m2. This achievement represents a substantial 140.7% increase compared with pure polybenzoxazine. Moreover, the flexural strength reaches 133.4 MPa, surpassing pure polybenzoxazine by 16.2%. And the modified system exhibits a 10% weight loss temperature (Td10) at 321.7°C, accompanied by a char yield of 27.6%. This holistic approach results in a notable enhancement of the toughness performance while concurrently maintaining the flexural strength and the thermal stability of the modified system. Consequently, the integration of soft core–soft shell nanoparticles emerges as a promising strategy for enhancing thermoset resin properties without undermining their existing exceptional attributes.Highlights The core–shell nanoparticles were made by dopamine and cellulose nanocrystals. The core–shell nanoparticles can enhance the toughness of polybenzoxazine. Nanoparticle‐matrix interactions and deformation led to improved properties.
