“…Photoresponsive polymers undergo chemical and physical microstructural changes upon light exposition [ 13 ]. These stimuli-responsive systems exhibit remarkable spatial specificity and can respond to a wide range of wavelengths, spanning from ultraviolet (UV) to infrared (IR), which makes them highly versatile [ 13 ]. Typically, these stimuli-responsive polymers are categorized as either UV sensitive or visible light sensitive [ 14 ].…”

“…In response, the network undergoes reversible or irreversible conformational changes. The magnitude and nature of the response can be finely tuned by varying the type of chromophore or the specific stimulus parameters, such as light wavelength, intensity, and exposure time [ 13 ]. It is instrumental to maintain bonding stability between the chromophore and the polymeric network, as non-covalently bonded species can lead to inconsistent and sluggish responses, ultimately impacting the efficiency of the system [ 14 ].…”

“…Typically, these stimuli-responsive polymers are categorized as either UV sensitive or visible light sensitive [14]. The design of photoresponsive systems involves a crucial step of selecting appropriate photoreactive functional groups, in addition to considering factors such as glass transition temperature (Tg) and free volume space, as discussed previously [2,13]. In essence, the photoreactive moieties, also known as chromophores, absorb light energy and undergo photoinduced reactions such as isomerization, dimerization, or cleavage [13,15].…”

The field of dental materials is undergoing rapid advancements in the pursuit of an innovative generation of dental polymeric restorative materials. There is a growing interest in the development of a distinct category of dental polymers that transcend the conventional role of inertly filling prepared cavities. Instead, these materials possess the capacity to actively detect and respond to alterations within the host environment by undergoing dynamic and controlled molecular changes. Despite the well-established status of stimuli-responsive polymeric systems in other fields, their implementation in dentistry is still in its nascent stages, presenting a multitude of promising opportunities for advancement. These systems revolve around the fundamental concept of harnessing distinctive stimuli inherent in the oral environment to trigger precise, targeted, predictable, and demand-driven responses through molecular modifications within the polymeric network. This review aims to provide a comprehensive overview of the diverse categories of stimuli-responsive polymers, accentuating the critical aspects that must be considered during their design and development phases. Furthermore, it evaluates their current application in the dental field while exploring potential alternatives for future advancements.

“…Physical comfort is associated with fabric properties and social acceptance, but thermal comfort is governed by heat, moisture, and airflow. Thermo‐physiological wear comfort manages heat and moisture transfer to keep the body thermally balanced while performing diverse activities [1–4] . Utilizing a variety of metrics including thermal conductivity, resistivity, absorptivity, diffusion, sorption, evaporation, wicking, and air/water permeability, researchers have investigated the thermal and moisture behaviour of clothing by modifying fabric structure [5–7] .…”

The surface of viscose fabric was successfully functionalized with 3‐aminopropyltriethoxysilane (APS) and 3‐methacryloxypropyl‐trimethoxysilane (MPS) in order to optimize its physicochemical characteristics and textile performances. The functionalization was optimized with silane monomer concentrations of 600 and 300 %, ethanol‐water ratios of 60 : 40 and 80 : 20, pH 3.5 and 5, and reaction time of 90 and 60 min at 30 °C, for MPS and APS, respectively. The modified viscose fabric was characterized by FTIR, TGA, DTG, SEM, and EDX. The FTIR spectra of the MPS and APS‐modified fabrics showed additional peaks at 825 cm−1 for Si−CH2 group and 1208 cm−1 Si−O−CH3, respectively, indicating the incorporation of silane coupling agents. The degradation temperatures of MPS and APS‐modified fibres were 342 °C and 328 °C, respectively, while the value for untreated viscose fibre was 319 °C. The elemental percentage of silicone on viscose fibre after modification was 2.6 and 4.2 for MPS and APS respectively. The silane‐modified viscose fibre shown enhanced tensile strength, water repellency, thermal stability, wrinkle recovery, and improved colour fastness quality. These improvements were due to the flexibility of Si−O bond and the fibre matrix interfacial strength properties. Hence, the modification somewhat enhances the physico‐chemical characteristics of viscose fibre.
