Abstract Liquid crystalline polymer (LCP) coatings offer avenues for the fabrication of devices with smart surfaces incorporating responsive topography, reflectivity, or polarization from their unique anisotropic optical and mechanical properties. LCPs have most commonly been made by photopolymerization reactive mesogens within confined cells. Here, an alternative method preparing LCP using ini...

STATEMENT OF PROBLEM Acrylic resins are prone to microbial adherence, especially by Candida albicans. Surface-charged resins alter the ionic interaction between the denture resin and Candida hyphae, and these resins are being developed as a means to reduce microbial colonization on the denture surface. PURPOSE The purpose of this study was to investigate the physical and mechanical properties...

Butyl lactate is a green solvent produced from renewable materials through the reaction of ammonium with n-butanol. It could be source material for valuable products such as propylene glycol, acrylic acid, its derivatives, and cyclic monomer polylactic acid (PLA)—lactate. In this study, we present novel non-catalytic interactions n-butanol carried out in temperature range 130–170 °C closed syst...

Abstract Surface modification of polyvinylidene fluoride (PVDF) hollow fibre membranes through simple chemical treatment is carried out to graft the surface with presence carboxylic acid groups. This provide means for TiO 2 immobilisation in subsequent stages photocatalysis application. The focus this study was identify highest degree grafting order abundant potential sites assembly. Both aceti...

Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads, which are the main component of the solid part of the cement. In this work beads of poly(methyl methacrylate-co-styrene) were synthesized by suspension polymerization. The objective of this study was t...

The functionalizing of a fiber surface by chemical may alter the physical and biological properties fiber. functionalization polypropylene (PP) selected monomers (1) acrylic acid (AA), (2) 2-hydroxyethyl methacrylate (HEMA), (3) 2-dimethyl amino ethyl (DMAEMA), (4) methyl acrylate (MA) studied using two different ultraviolet (UV) irradiation techniques, simultaneous UV (SUVF) pre-UV (PUV). Base...

Early history of dentin bonding Attempts to develop an adhesive system which bonds acrylic resins to the tooth structure started in the early 1950s. In 1949, an adhesive system capable of bonding acrylic resin to the tooth structure was invented by Hagger; it was composed of glycerophosphoric acid dimethacrylate (GPDM) and sulfinic acid as the catalyst. In his patent, shear bond strengths of ac...

The prevalence of stomatitis, especially caused by Candida albicans, has highlighted the need of new antifungal denture materials. This study aimed to develop an antifungal heat-curing resin containing quaternary ammonium monomer (dimethylaminododecyl methacrylate, DMADDM), and evaluate its physical performance and antifungal properties. The discs were prepared by incorporating DMADDM into the ...
