Title: Carl-Gustaf Golander: Inventor of a Surface Modification Method
Introduction
Carl-Gustaf Golander is an inventor associated with Stockholm, Sweden, and Ird-Biomaterial AB. His recorded patent work concerns modifying solid surfaces through the adsorption of a polymeric complex, with the aim of imparting charges or attaching reactive compounds. Golander is credited with 1 patent.
Latest Patents
Golander’s listed patent is “Surface Modified Solid Substrate and a Method for Its Preparation.” It describes a substrate carrying an adsorbed complex formed from a polymeric cationic surfactant containing primary amino nitrogens and secondary and/or tertiary amino nitrogens, together with a dialdehyde whose aldehyde groups are separated by one to four carbon atoms.
The patent explains that the complex may also bond with an anionic compound, followed, if desired, by alternating additions of further cationic and anionic compounds. This approach can impart positive or negative charges to the substrate, or make use of reactive groups in the bonded compounds.
The preparation method involves contacting the substrate with the surfactant and dialdehyde under conditions that form a complex capable of adsorbing onto the surface. The materials are preferably used in a polar solvent, such as water. Complex formation takes place above pH 8, while charge creation is preferably carried out below pH 7.
Career Highlights
Golander’s documented patent contribution focuses on surface modification and the preparation of modified solid substrates. The invention outlines a method for controlling surface properties through complex formation and subsequent ionic bonding.
