“…In fact, wound healing is a dynamic process consists of several cellular and biochemical activities and overlapping phases including inflammation, new tissue formation, and remodeling. 1,2 Unfortunately, human body cannot heal dermal injuries 35 completely. Since skin forms a protective barrier around the body, damage to the dermis may cause several problems like severe dehydration as well as infection.…”

Thiol-ene polymerization and one electron transfer reaction were simultaneously utilized in the present 10 study for the preparation of semi-IPNs composed of a thermoplastic polyurethane elastomer, crosslinked poly(N-isopropylacrylamide) and silver nanoparticles (AgNPs). Application of these materials as thermoresponsive and antibacterial wound dressings with proper mechanical properties, efficient handling of wound exudates and easy peeling from wounded area were examined.Thermoresponsivity of membranes was elucidated via differential scanning calorimetry and measuring water absorption at 15 different temperatures. Ease of removal of designed dressings from wound bed was confirmed based on qualitative examination of adhered cells to dressings at temperatures lower and higher than lower critical solution temperature of the prepared membranes. The proper bulk hydrophilicity and water vapour transmission rate of designed dressings showed their ability for managing of wound exudates. The potential ability of prepared dressings for protection of wound bed from external forces over entire period 20 of healing was confirmed by their excellent tensile properties even at fully hydrated state. In situ generation and dispersion of AgNPs into the matrix of dressings, as well as the size of these particles were elucidated by EDX and TEM methods. MTT assay against human dermal fibroblast cells performed on dressings with and without AgNPs was approved their appropriate cytocompatibility. And finally, the measured antimicrobial activity of dressings against different gram positive and gram negative bacteria as 25 well as a fungal strain showed promising efficiency of impregnated AgNPs for combating microorganisms.

“…In the same sense, allyl-, acrylate-, as well as vinyl ether derivatives of castor oil were used together with multifunctional thiols for the preparation of UV curable resins. [29] Moreover, Bantchev et al [30] investigated thiol-ene addition reactions of canola and corn oil with butanethiol to yield sulfur-containing compounds with possible applications as lubricants to improve wear and friction properties. Very recently, thiol-ene chemistry was also applied for the preparation of bio-based telechelics [31] and soy-based thiols and enes were formulated with allyl triazine resulting in tack-free coating films after UV curing.…”

Thiol‐ene additions of methyl 10‐undecenoate, a castor oil derived renewable platform chemical, were studied with the goal of preparing a set of renewable monomers. Good to excellent yields were obtained for these solvent and initiator free thiol‐ene additions. The resulting monomers were then polymerized using TBD as a catalyst, to linear as well as hyperbranched polyesters that also contain thio‐ether linkages. All thus prepared polymers were fully characterized (NMR, GPC, DSC, and TGA) and the results of these investigations will be discussed within this contribution. The thermal analysis of these polymers revealed melting points in the range from 50 to 71 °C. Moreover, no significant weight loss was observed below 300 °C.magnified image

Der wesentliche Beweggrund Beschichtungen auf Basis nachwachsender Rohstoffe (Nawaro) zu entwickeln und zu verwenden ist nach wie vor die Erwartung, dass diese Produkte in Zukunft durch die stetig steigenden Erdölpreise ökonomischer werden. Auch die Endlichkeit des Erdöls und die damit verbundene hohe Abhängigkeit gegenüber den OPEC-Staaten sind Gründe, alternative Ressourcen zur Herstellung von Beschichtungsstoffen zu finden. Dieser Beitrag soll den derzeitigen Stand der Technik und auch neue Trends der stofflichen Nutzung von nachwachsenden Rohstoffen speziell für die Lackindustrie näher beleuchten. Es werden Möglichkeiten aufgezeigt, die Nawaro bei der Synthese von Lackharzen bieten. Dabei werden die Schwerpunkte auf die Chemie der pflanzlichen Öle und Saccharide gelegt und dabei die klassische Chemie und auch neuere Methoden - wie die enzymatische Katalyse oder die Industrielle Biotechnologie - aufgeführt, die zur Herstellung von Bindemitteln für dauerhafte Industrie- und Bautenlacke sowie Druckfarben verwendet werden können. Spezielle Anwendungen, wie z. B. Food-Coatings, medizinische Beschichtungsstoffe und biologisch abbaubare Beschichtungen, werden nicht berücksichtigt
