«ΑΝΤΙΜΙΚΡΟΒΙΑΚΗ ΧΡΗΣΗ ΕΝΟΣ ΔΙΑΦΑΝΟΥ ΦΙΛΜ "ANTIMICROBIAL USE OF A TRANSPARENT FILM
ΥΛΙΚΟΥ ΠΟΛΥ ΟΥΡΕΘΑΝΗΣ ΚΑΙ ΧΑΛΚΟΥ» POLY URETHANE AND COPPER MATERIAL"
Τεχνικό πεδίο Technical field
Η παρούσα εφεύρεση σχετίζεται με την επικάλυψη επιφανειών με τις οποίες έρχεται συχνά σε επαφή ο άνθρωπος. Ιδιαίτερα κοινόχρηστες επιφάνειες οι οποίες δυνητικά αποτελούν εστίες διασποράς μικροβίων, είναι δυνατόν να επικαλυφθούν με ένα αυτοκόλλητο φιλμ θερμοπλαστικής πολυουρεθάνης (TPU) που περιέχει χαλκό (Cu) . The present invention relates to the coating of surfaces with which man frequently comes into contact. Especially shared surfaces that are potentially hotbeds of germs can be covered with an adhesive thermoplastic polyurethane (TPU) film containing copper (Cu).
Τεχνική υποβάθρου Background technique
Τεχνικές που χρησιμοποιούνται σήμερα αφορούν κυρίως την συνεχή απολύμανση επιφανειών σε κοινόχρηστους ή και συχνόχρηστους χώρους με απολυμαντικά που περιέχουν αλκοόλες ή τεταρτοταγή άλατα του αμμωνίου. Σε χώρους που υπάρχει μεγάλο μικροβιακό φορτίο όπως νοσοκομεία μπορούν να χρησιμοποιούνται απολυμαντικά με δραστικές ουσίες είτε τις παραπάνω είτε αλδεΰδες είτε υποχλωριώδες νάτριο. Techniques used today mainly concern the continuous disinfection of surfaces in common or frequently used areas with disinfectants containing alcohols or quaternary ammonium salts. In places where there is a large microbial load such as hospitals, disinfectants with active substances either the above or aldehydes or sodium hypochlorite can be used.
Η παρούσα εφεύρεση είναι ένα σύνθετο υλικό που αποτελείται από πολυουρεθάνη και χαλκό. Χαρακτηρίζεται από εφάπαξ κόστος και διαρκή μείωση του μικροβιακού φορτίου σε καλυμμένες με αυτό επιφάνειες. Παράλληλα είναι διαπερατό στο φως και έχει χαμηλότερο κόστος από τον καθαρό χαλκό. The present invention is a composite material consisting of polyurethane and copper. It is characterized by a one-time cost and a permanent reduction of the microbial load on surfaces covered with it. At the same time, it is permeable to light and has a lower cost than pure copper.
Η εφεύρεση είναι υλικό σε μορφή φιλμ που περιέχει 97 έως 98% wt. TPU και 2% έως 3% wt. Cu. Έχει διαπιστωθεί πειραματικά το ανωτέρω υλικό φέρει τις αντιμικροβιακές ιδιότητες του χαλκού, αφού επέρχεται μείωση του μικροβιακού φορτίου και ιδιαίτερα του ιικού φορτίου στην επιφάνειά του. Το υλικό είναι φιλμ 2 διαστάσεων κατάλληλου πάχους που επικολλάται σε επιφάνειες με σκοπό την συνεχή μείωση μικροβιακού, μυκητιακού και ιικού φορτίου. Η χρήση αυτού του υλικού αφορά φιλμ στα πλαίσια που εμπίπτουν στην χημική σύστασή του. The invention is a material in film form containing 97 to 98% wt. TPU and 2% to 3% wt. Cu. It has been experimentally established that the above material has the antimicrobial properties of copper, since there is a reduction in the microbial load and especially the viral load on its surface. The material is a 2-dimensional film of appropriate thickness that is affixed to surfaces in order to continuously reduce microbial, fungal and viral load. The use of this material concerns films in the contexts of its chemical composition.
Η εφεύρεση σχετίζεται με την αξιοποίηση των εγγενών αντιμικροβιακών και αντιιικών ιδιοτήτων του χαλκού, αλλά και των φυσικών και μηχανικών ιδιοτήτων του πολυμερούς. Ο χαλκός έχει ηλεκτρονιακή διαμόρφωση [Ar]3d<10>4s<1>. Η κυτταρική μεμβράνη των μικροβίων έχει ένα σταθερό ηλεκτρικό δυναμικό. Ο χαλκός έχει ένα ασύζευκτο ηλεκτρόνιο στο 4s ατομικό τροχιακό. Ο χαλκός ερχόμενος σε επαφή με βακτήρια διαταράσσει το δυναμικό της μεμβράνης τους. Η μεμβράνη των βακτηρίων ανοίγει τρύπες, ιόντα χαλκού και σωματίδια χαλκού μπαίνουν στο εσωτερικό του βακτηρίου, προσδένονται στα ένζυμα που είναι απαραίτητα για την επιβίωσή του. Ως αποτέλεσμα το βακτήριο πεθαίνει. Το πολυμερές PU χρησιμοποιείται για την κατασκευή αδιάβροχων μεμβρανών για την κάλυψη επιφανειών. Όταν έχει κατάλληλη σύσταση των μακρομοριακών αλυσίδων ώστε να έχει θερμοπλαστικές ιδιότητες αναφέρεται ως TPU. The invention is related to the exploitation of the intrinsic antimicrobial and antiviral properties of copper, but also of the physical and mechanical properties of the polymer. Copper has an electronic configuration [Ar]3d<10>4s<1>. The cell membrane of microbes has a constant electrical potential. Copper has an unpaired electron in the 4s atomic orbital. Copper coming into contact with bacteria disrupts their membrane potential. The membrane of the bacteria opens holes, copper ions and copper particles enter the interior of the bacterium, attach to the enzymes necessary for its survival. As a result the bacterium dies. PU polymer is used to make waterproof films to cover surfaces. When it has a suitable composition of macromolecular chains to have thermoplastic properties it is referred to as TPU.
Στον Πίνακα 1 παρουσιάζονται αποτελέσματα μετά από 30 min επαφής του υλικού με μία αρχική συγκέντρωση βακτηρίων και ιών. Table 1 shows results after 30 min of contact of the material with an initial concentration of bacteria and viruses.
