“…Citric acid is a relatively small and multifunctional monomer with pendant functional groups that allow future ester bond-crosslink and hydrogen bonding [15,16]. Fatty acids are relative long monomers with a carboxylic functional group that with chemical modification of doubledouble bond of unsaturated fatty acids allows the formation of crosslinked polymer structures [17]. The present study focuses on the synthesis and characterization of novel polymeric materials from biodegradable monomers that respond to pH and temperature stimuli.…”

Polyglycerol-based hydrogels from biodegradable raw materials were synthesized by crosslinking reactions of polyglycerol with citric and fatty acids. Three hydrogels were studied varying molar ratios of crosslinking agent. It was found that crosslink amount, type, and size play a crucial role in swelling, thermal, mechanical, and stimuli-responsive properties. The hydrogels absorption capacity changed in response to temperature and pH external stimuli. The hydrogel with the highest swelling capacity absorbed more than 7 times its own weight at room temperature and pH 5. This material increased 14 times its own weight at pH 10. Creep-recovery tests were performed to study the effect of crosslinking agent on mechanical properties. Deformation and percentage of recovery of synthesized hydrogels were obtained. Formation of hydrogels was confirmed using FTIR, and physicochemical properties were analyzed by Scanning Electron Microscopy (SEM), Differential Scanning Calorimetric (DSC), and Dynamic Mechanical Analysis (DMA). This paper aims to give a contribution to biobased hydrogel knowledge from chemical, physicochemical, and mechanical point of view.

“…Moreover, degradation of sensitive molecules which decompose at a high reaction temperature is avoided since photopolymerization can be conducted at room temperature. Additionally, crosslinking density of hydrogels can be controlled by adjusting UV exposure time, UV exposure power, and photoinitiator concentration [12,13,15]. To utilize the advantages of photopolymerization technique, photopolymerizable chitosan which facilitates to compose chemically polymeric network has been synthesized by using different materials and used for a number of biomedical applications.…”

In this study, a novel route was developed to fabricate chitosan-based hydrogel by using photopolymerization technique. Firstly, glycidyl methacrylate (GMA) grafted onto the chitosan (CTS) backbone to produce chitosan derivative product having photopolymerizable groups (CTS-g-GMA). Following, CTS-g-GMA and PEGDA are subjected to photopolymerization to form chemically crosslinked hydrogel. The chemical structure of the obtained chitosan-based hydrogel was characterized by Fourier transform infrared (FT-IR) analyses. Thermal behavior of hydrogel was determined by thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). The thermal analyses showed that (CTS-g-GMA)-PEGDA had higher thermal stability than neat chitosan. Water uptake capacities (swelling ratio) of hydrogels obtained by using different UV exposure time were determined gravimetrically. From the swelling test result, it was observed that exposure time has the effect on the water uptake capacity of hydrogels. Additionally, cytotoxicity test for chitosan-based hydrogel was carried out by using L929 fibroblasts. All of the obtained results demonstrated that chitosan-based hydrogel fabricated in this work could be used for biomedical applications in future works.

“…These photoresponsive molecules can be (2π+2π) dimerized under UV irradiation and are usually grafted onto polymers as photocrosslinking moieties. 47 Templates Templates for nanolithography. The aforementioned nanopatterns obtained by photolithography are known as the top-down approach, in which the optical immersion technology (using a wavelength of 193 nm) has reached the diffraction limit, making it extremely difficult to scale below dimensions of 22 nm.…”

Renewable polymers have attracted extensive research interest as substitutes for fossil fuel-based materials because they are sustainable and biodegradable. With the rapid increase in the applications of electronic devices, the integration of renewable polymers with electronics not only enhances the economic benefit of waste natural resources but also conserves our environment. In this review, an overview of renewable materials used in electronics, including passive components (that is, substrates, photoresists, templates and dispersion agents) and active components (that is, luminescence layers, protontransporting layers and charge-trapping layers), as well as their future perspective is provided. The relationships between chemical structures, their morphologies and the device characteristics will be discussed. It is hoped that this review will stimulate research and generate interest in applications of renewable materials for the electronics industry.
