Abstract

Polihidroksialkanoati (PHA) su poliesteri koji privlače veliku pažnju zbog svoje biorazgradivosti i biokompatibilnosti, što ih čini vrlo primjenjivima u različitim industrijama. Kako bi se poboljšala svojstva i smanjili troškovi proizvodnje, intenzivno se razvijaju kompoziti i mješavine na bazi PHA. PHA se mogu kombinirati s raznim polimerima, aditivima i punilima kako bi se postigla šira paleta svojstava i funkcionalnosti. Razvoj ovih materijala proširuje primjenu PHA te promiče održivost i ekološku svijest u društvu. U ovom preglednom radu razmatrane su mješavine PHA s polimerima poput polilaktidne kiseline (PLA), polikaprolaktona (PCL), polibutilen sukcinata (PBS) i poliamida (PA), koje omogućuju prilagodbu mehaničkih i termičkih svojstava prema specifičnim zahtjevima primjene. Pored toga, istraženi su kompoziti PHA s različitim punilima, uključujući škrob, kitozan, celulozu i drvo, kako bi se poboljšala čvrstoća, elastičnost i smanjili troškovi konačnih materijala. Rad naglašava važnost daljnjih istraživanja u razvoju i optimizaciji ovih materijala, kako bi PHA postao široko primjenjiv u industrijama koje zahtijevaju održive i ekološki prihvatljive opcije.

Abstract (english)

Polyhydroxyalkanoates (PHA) are polyesters that have attracted a lot of attention due to their biodegradability and biocompatibility, making them highly applicable in various industries. In order to improve properties and reduce production costs, PHA-based composites and blends are being intensively developed. PHAs can be combined with various polymers, additives and fillers to achieve a wider range of properties and functionalities. The development of these materials expands the application possibilities of PHA and promotes sustainability and environmental awareness in society. In this review, blends of PHA with polymers such as polylactic acid (PLA), polycaprolactone (PCL), polybutylene succinate (PBS) and polyamide (PA) were considered, which allow tailoring of mechanical and thermal properties to specific application requirements. In addition, PHA composites with various fillers, including starch, chitosan, cellulose and wood, were investigated to improve the strength and elasticity and reduce the cost of the end products. The paper highlights the importance of further research to develop and optimise these materials so that PHA can be widely used in industries that require sustainable and environmentally friendly options.
