New hand sanitizer designs with eco-friendly components such as aloe vera and copper can allow pharmaceutical companies to bring enhanced applications onto the market while demonstrating simple and inexpensive preparations associated with improved microbial effectiveness. Alcoholic or non-alcoholic hand rubs are distinctively major classes of hand sanitizer platforms that can be prepared into hydrogels to address solutions for improved formulations. The innovative-utility of these hydrogels seems to be limited only by their ingredients and thus novel materials like copper or aloe vera can lead to optimization of anti-bacterial and anti-viral properties of sanitizers, and therefore a diversified product that may aid further research related to high demands of safe and sustainable materials to combat the current pandemic of COVID-19. The customized designs of starch or cellulosic hydrogels may ensure the diversity and right quality of incorporating these components needed for biocidal activity against microbes in the suggested hand sanitizers. Furthermore, the discussed sanitizer of copper and aloe vera combined in starch or cellulosic hydrogels are believed to exert enhanced texture, tone, and elasticity upon topical application due to their properties that may delve into the enzymatic activities required for less prevalence of skin lesions commonly known in traditional hand sanitizers.

“…The solvent molecules can interact with each other as well as with the polymer structure, and also migrate in and out of the swollen aggregate. The theory of mass transport in the continuum solids dates back to Tanaka and Fillmore (1979), and have been further developed for the description of coupled deformation and diffusion with application to the response of hydrogels, including swelling and deswelling induced by mechanical deformation and forced fluid permeation (Bayat, Wang, & Baghani, 2020;Duda, Souza, & Fried, 2010;Sauerwein & Steeb, 2020). The purpose of this work is to develop a thermodynamically consistent large-deformation theory on the continuum level for the description of EVA polymer-solvent system in the PV recycling, so as to provide guidance to the design of experimental procedures for the nondestructive recovery of ultrathin and brittle silicon wafers.…”

“…Models are also used to extract material properties from materials with linear stress–strain behaviors. For highly elastic materials, several models have been developed to understand the stress–strain behavior of polymeric and other soft stretchable materials. − In general, these hyperelastic materials display characteristics such as strain hardening, where the stress rapidly increases beyond some critical strain. Without these models, this would be difficult due to the highly nonlinear mechanical responses, which makes standard linear relationships much less useful for their characterization.…”

Modeling Approach to Capture Hyperelasticity and Temporary Bonds in Soft Polymer Networks

Hyperelastic models developed by Gent, Ogden, and Dobrynin are modified to include a strain rate-dependent element. This strain rate dependence accounts for the breaking of temporary bonds in materials as opposed to the stretching of polymer chains. Accounting for the strain rate dependence in a material's mechanical response gives the ability to extract the modulus due to temporary and permanent bonds, strain hardening, and the relaxation time of dynamic materials. These modified models were tested against a wide range of elastomeric materials. The models were applicable across many network polymers, showing clear effects of temporary bonds in the material. Template spreadsheets for the developed models will be publicly and freely available, facilitating the application of these models to a range of complex soft materials.
